Romeo (Saif Ali Khan) lives the high life as a pampered pooch, until his owners move away and kick him to the curb. Now facing life on the mean streets of Mumbai, Romeo knows he must adapt, or die. But things are looking up for this smooth-talking canine. He meets and falls in love with the ravishing Laila (Kareena Kapoor), and wants to live happily ever after with her... if only he can get past the neighborhood's most feared crime lord: Charlie Anna (Jaaved Jaaferi).
