His best friend is Prem Chopra (Ajay Devgn), who is married to Jhanvi Chopra (Bipasha Basu). Jhanvi runs a broken down gymnasium owned by Prem's family and Prem spends his time mechanically modifying cars.

Veer and Prem need Rs. 500,000 to register Prem's car for an illegal race (if they win they will get Rs. 5,000,000).
