Welcome’s Uday Shetty (Nana Patekar) and Majnu bhai (Anil Kapoor) have left the underworld to become businessmen and are involved with two posers, Chandni (Ankita Srivastava) and Maharani (Dimple Kapadia). Appa, Uday’s father, springs a surprise on them by bringing another daughter Ranjana (Shruti Haasan) from his third marriage and asks them to get her married to someone from a good family. Maharani has a condition - only after Ranjana is married will Chandni marry one of them. Who should they call in this hour of need, but Dr. Ghungroo (Paresh Raval)? As fate would have it, Ghungroo’s wife Supriya has a child from a past marriage, Ajay (John Abraham). Uday and Majnu are thrilled and fix Ranjana’s wedding with Ajay - not knowing that he is a menacing Mumbai goon.
