Crazy is the story of JK(Aarya), Seenu(Premji) and Naaki(Sathanam) who work for a news paper. One fine day JK’s girlfriend, Hansika Motwani asks JK to deliver a parcel to one of her friends. As JK is busy, he asks Naaki to deliver the parcel. In an interesting turn of events, Naaki misplaces the parcel and accidentally delivers something else to the evil gangster Nasser. Hell breaks out loose when Nasser finds out that the parcel has been misplaced, and in turns comes fuming after the three friends. Rest of the story is as to how these friends survive the evil torture of the goons and come out successfully.
