Farhan Qureshi and Raju Rastogi want to re-unite with their fellow collegian, Rancho, after faking a stroke aboard an Air India plane, and excusing himself from his wife - trouser less - respectively. Enroute, they encounter another student, Chatur Ramalingam, now a successful businessman, who reminds them of a bet they had undertaken 10 years ago. The trio, while recollecting hilarious antics, including their run-ins with the Dean of Delhi's Imperial College of Engineering, Viru Sahastrabudhe, race to locate Rancho, at his last known address - little knowing the secret that was kept from them all this time.

Mumbai-based Ramvilas Sharma has just broken-up with Sanjana Mahadik, a former bar dancer, with whom he had a six month relationship. His private-detective friend, Nandan Pandey, attempts to counsel him over this break-up, and even encourages him to meet other women. Ramvilas does meet with a homeless woman, Koel Datta, befriends her, and even brings her to spend the night in his flat but will be interrupted when Sanjana will come to take her belongings back and will leave a bag full of cash. Everyone will find their respective lives turned upside when they will be 'interrogated' by a suave French-speaking crook, Lucky Sardana, after the bag goes missing.
