The story revolves around a young boy with marginal IQ whose life changes dramatically when he begins to experience the different expressions of food that fill the taste buds and have varied reactions on people who savour them.^[1]

Rainbow Jelly is the first-ever attempt in Food Fantasy Film genres, perhaps India’s first, made in Bengali language. The story of the film is an outcome of Ghosal's two years of research on Taste Theory & Ayurveda. The film won the Best Feature Film for Soukarya Ghosal at Hiralal Sen Award in 2019 from FFSI.^[2][3]

The film based on a 12 years old orphan special child 'Ghoton',^[4] who is a magical cook. He is not sent to school and is captivated in his own dilapidated ancestral house by his only guardian 'Gondaria', his maternal uncle. Gondaria is a foodie & selfish character man who treats Ghoton like his servant. He always blackmails the boy saying that Ghoton's father who was an acclaimed scientist had left a treasure for his son. Only if Ghoton serves Gondaria till he turns 18 years, he can have the treasure. The innocent boy believes his uncle till a mysterious woman 'Poripishi'(aunt fairy) comes to him & claims, that she only can turn his dream of treasure true. That too within 7 days. For which she would secretly cook seven different dishes of food on behalf of Ghoton, of 7 different tastes ie, Sweet, Sour, Salty, Spicy, Pungent, Astringent & Bitter for the coming 7 days. With every taste & colour of the food Gondaria's mood changes accordingly. Sweet-Red dish makes him lovable. Sour-Orangy makes him repent. Salty-Yellow makes him contemplative. Spicy-Green makes him sad. Blue-Pungent makes him tense. Indigo-Astringent makes him hasty and the Bitter-Violet makes him angry. Finally, on the 8th day, Poripishi prepares a special dish with the residues of the prior seven dishes. This is a magical food - Rainbow Jelly which consists of all the tastes & colours of the universe. If anyone has it the person changes completely into a new human being. Ghoton serves that to Gondaria. After this a magical change occurs in Ghoton's life with which he not only discovers the hidden treasure of his father but also comes across the actual truth of his life. The truth that no one knew. The truth never could have been revealed if Rainbow Jelly wouldn't come into his life.^[5][6][7]
