'Hey Bro' is a comedy action drama film that depicts the journey of the very cute, innocent & loveable 'GOPI' (Ganesh Acharya) from a small village in Rajasthan to Mumbai in search of his 'TWIN' brother (Maninder) & mother (Indrani) separated from him at birth. He doesn't have an address or any picture of his brother & mother, but to fulfil his DADAJI's (Prem Chopra) wish; he leaves the village in their search with his 'own picture' naively believing that his brother would look 'just like him' as 'twins always do', coz he had seen that in a lot of movies. 

What follows is a roller coaster ride of fun, comedy & entertainment. The 'hunt' for his brother lands the 'Bhola' GOPI, in a lot of crazy situations, the wrong side of the law as well as a lawbreaker 'Land Mafia Don' BABA (Hanif Hilal).
