24-year-old Jenna gave up her job as a vet's assistant to become a paramedic. An hour into her first shift, Jenna and mentor Cleone rush to the aid of an elderly man in cardiac arrest. At college she practised CPR on dummies ... but now for the first time a human life rests in her hands.

Starting his new career is former tyre fitter, John Williams. Under the mentorship of Jordan, John heads out on his first emergency call – a 26-year-old girl is critically ill with fever.

As one group of trainees hit the road, the next class of students start their journey at college. Former fiery, Reynir, has been waiting seven years for this moment. And from day one the pressure is on. Educators stage a fake heart attack in the classroom to test the student's reaction time. When only 2 out of 50 trainees go to the aid of the victim, the immensity of the challenge ahead becomes apparent.

Jenna and Cleone arrive at a street party turned alcohol fuelled brawl, a reveller's been glassed in the face. But there's a hitch, he's refusing to leave the party.

At college the trainees break open the equipment bags. As a former Coff's lifesaver, Blake Field knows about first aid. But taking correct pulse, handling stethoscopes and applying neck braces is a very different game. As Blake discovers, one tiny mistake can result in dire consequences for his patient.

• Meanwhile, students at college receive their uniforms and learn the best techniques when managing a stretcher

Mentor Jordan has witnessed hundreds of car crashes in his career, but at his first, trainee John has little idea what to expect. Out in suburbia Jenna and Cleone make a grim discovery. A man hasn't seen his neighbour for 12 days and as the team arrive, their worst fears are confirmed.

For the students at college one of the most anticipated days of the entire course has arrived - their uniforms. But the euphoria doesn't last long, today's lesson, stretcher technique, the students discover, it's harder than it looks.

A high alert drug overdose propels John and Jordan into King Cross. It's a brutal lesson in the unpredictable effects of illicit drugs. Carleigh faces a life and death situation. A man has collapsed during the family's Sunday dinner. With a history of heart problems, and now vomiting and sweating, he could be in serious trouble.

• Evan begins his first shift and is called out to a car accident, where a car has crashed into an electricity pole
• Jenna is called out to assist after a man suffers from an epileptic seizure and is unconscious
• Reynir, on his first observation shift, is called out to an attempted suicide

The driver, Guy, is stable but extracting him from the wreck brings its own risks. It's almost midnight when Jenna & Cleone are called to a suspected epileptic seizure. As the patient swings in and out of consciousness it proves a tricky case to solve.

After mid-term exams the students are about to get their first taste as front line paramedics. They're about to spend 3 days observing on the road. The first job Reynir will attend as a student paramedic is one that even seasoned paramedics find confronting. A young man has tried to hang himself.

• Rebecca is called out to assist with injuries resulting from a brawl in Kings Cross
• John is called out to assist at an old-age home after a resident falls
• Meanwhile, at college, the recruits learn the most effective way of assisting drivers who are involved in car accidents

65 km down the road in Sydney's Kings Cross jungle the results of a drunken brawl put Rebecca, a mother of three, to the test. It's the first time she's been to the red light district and already she has blood on her hands - literally. However, for rookie John his day is an eye opener for different reasons. The frailty and loneliness of old age hits home as he sees a side of life he's never experienced before.

At Paramedic College Danielle and Reynir are feeling the pressure of their new career. They're learning how to get injured drivers out of car wrecks. Get it wrong and their patient could end up a paraplegic.

• Rebecca is called to assist a young girl with breathing difficulties
• Evan is called to a car accident, after a man has rolled his car several times and suffers serious injuries
• Meanwhile, at college, recruits are being assessed on their CPR skills

On Sydney's outskirts 82-year-old Bob has rolled his car several times. It's up to Evan, in the role of treating paramedic for the first time, to treat his serious injuries. It is a big responsibility and puts the young rookie to the test. And unusual scene John Williams the trainee, meets John Williams the patient. Will the real John Williams please stand up?

At Paramedic College trainees are nearing the end of their 8 weeks intensive theory and it's crunch time. Blake and Reynir must show their CPR skills in a simulated cardiac arrest scenario. The patient has stopped breathing. They'll need to show instructors they're ready to deal with real life heart attacks out on the road.

• Jenna responds to her first pedestrian collision
• Rebecca is called to assist with a 67-year-old cancer patient in severe pain
• Meanwhile, at college, recruits are preparing for their final assessments, including treating a simulated trauma patient

If Reynir and Blake fail this test, they could be out of a job.

Jenna's been out of college for eight weeks with mentor Cleone. Today she is called to her first pedestrian collision. A car has struck a teenage-boy and, with pedestrian deaths accounting for about 13% of all road fatalities, Jenna's patient is lucky to be alive - although it is the injuries Jenna can not see that have her worried. Compassion is perhaps the biggest pre-requisite to becoming a Paramedic and after two months as a trainee, Rebecca's had plenty of time to reflect on this very human quality. When her father was dying of cancer, it was the compassion shown to him by a nurse that made Rebecca change careers and become a Paramedic. Now the mother of three is called to a job close to her heart when a 67-year-old cancer patient is in great pain.

It is a Saturday night, the full moon is out and a drug overdose is Reynir's first official job as a paramedic. It is an unpredictable and potentially explosive situation for the fresh-faced recruit. For rookie paramedics, dealing with situations on the street is very different from the classroom environment. Despite the best training possible, nothing can prepare them for the unforeseeable circumstances that confront them on a daily basis. As for young Blake, he manages to scrape through his final test at College but his real test now awaits him. Life on the road as a paramedic.

• Blake begins his first shift after college and is called out to a lady who is believed to be suffering from swine flu
• Rebecca is called out to assist a young woman who has collapsed on the road, and has possibly had her drink spiked

Saturday nights in Sydney are never quiet for a Paramedic. Trainee Rebecca and her mentor Chris are called to the aid of a young girl who is left collapsed and vulnerable on the side of a busy road. Her story rings alarm bells of a spiked drink.

As more and more people drive into the city to paint the town red, probationer John is called to a five-car pile up on a major highway. His thoughts drift back to his first motor vehicle accident when he wasn't so sure on his feet.

• Reynir is called to a situation at a train station, after a man collapses in cardiac arrest

In Sydney's Central Railway station a businessman is about to make a huge impact on the young trainee. As the man walks to a train, security cameras capture him collapsing to the ground—he has had a heart attack. Minutes later a team of paramedics, including Reynir, rush to treat the man. It is Reynir's first cardiac arrest and the first time he has used a defibrillator in a real-life situation. Only 3% of people who suffer cardiac arrest outside hospital survive. If the man does pull through he will be one of the lucky few.

At the end of 3 months on-road training, it's time for Jenna, Evan, Rebecca and John to say goodbye to their first.
