The show began with a short video introduction featuring Rihanna sitting on a throne wearing a black coat and a short red wig. The middle screen splits revealing Rihanna inside a purple ball wearing an electric blue dress. She begins singing "Only Girl (In the World)" surrounded by her dancers all wearing bright neon costumes. The next song, "Disturbia", follows with Rihanna taking off the blue dress and dancing around in a colorful daisy duke, leading into "Shut Up and Drive" where a car covered in graffiti is present in the middle of the stage. The first segment ends with "Man Down" where Rihanna gets inside the car and descends beneath the stage. The first video interlude titled "Le Sex Shoppe" features Rihanna dressed in white dress and a suit smoking a cigar while the words "sex" and "temptation" are whispered throughout the video. The second segment begins with a cover of Prince's "Darling Nikki" where Rihanna, dressed in a suit and holding a cane, rubs against her female dancers. The song moves into "S&M" where her female dancers remove her suit to reveal a tight black leotard and chain her to the stage. After a pillow fight with her male dancers, Rihanna then performs "Let Me", followed by "Skin" where Rihanna brings a fan onstage and gives him/her a lap dance as she descends back beneath the stage for a costume change. A brief guitar solo follows performed by Nuno Bettencourt. Rihanna returns to the stage atop a pink tank shooting puffs of smoke, with her and her dancers dressed in military gear, to perform "Raining Men". After climbing out the tank, Rihanna then performs "Hard" dancing around the stage while her dancers wield pink rifles. A mashup of "Breakin' Dishes" and Sheila E.'s "The Glamorous Life" is performed next, followed by another mashup of "Run This Town" and "Live Your Life" with Rihanna leaving the stage for another costume change.

The second video interlude features Rihanna wearing a red dress while waving sheets of chiffon in the air and ends with the spoken line: "I hate that I love you."

The song then moves into a solo version of "Hate That I Love You" with Rihanna sitting in a chair next to the guitarist. The segment ends with "California King Bed" with smoke covering the stage floor, followed by another guitar solo by Bettencourt.
