Bad Boy is a romantic comedy that revolves around a good-for-nothing boy (Namashi Chakraborty) who belongs to a middle-class family and dreams of becoming rich without doing anything. He falls in love with a studios girl (Amrin Qureshi) who comes from a conservative family. The girl’s father outrightly rejects him that leads to funny conflict and situations. The remaining story is about how they struggle and patch up things by overcoming all family obstacles.
