In Gayb, Vishnu Prasad is a loser. Lacking self-confidence and the attitude to lead an interesting life, things always go wrong with him. Gayab shows his unmatched knack of attracting problems, Vishnu's life doesn't get any easier courtesy a nagging mother who takes pride in beating him up at the slightest opportunity! His father (in Gayab), who is a henpecked husband, is too petrified to speak, let alone take his side. His friends show their concern by designating him as the undisputed king of idiots. Mohini, the love of his life, doesn't even know of his existence and her boyfriend wants to break his bones. As if all this was not enough... God then proceeds to make him invisible! ...to make him 'Gayab'. What happens next?
