His wife, Mitali, is in a particularly bad mood and Rahul suspects that she might know about his little escapade last night. Rahul starts chasing his night - trying to retrieve it - trying to find out what really happened.
His friends Saxena and Amit are going through their own marital crisis of sorts. Driven to his wits end, he realizes that he must seek Sophia out to restore his sanity.
