Naina and Sameer are asked to deliver a speech about the ill-effects of smoking by the principal. Seeing the two together, the other girls in the school feel jealous of Naina. Later, Naina sees Sameer smoking on the roof. Sameer throws the cigarette bud in the air and it, by chance, falls inside the chemistry lab, resulting in a fire. Then, Naina is asked by the principal to reveal the name of the student who threw the cigarette bud in the lab. Will Naina reveal the truth this time too?
