The film begins with the promise of a prolonged flashback: Vicky (Amitabh), sporting a dash of grey in his hair, has been just released from jail. He is received by a sympatico Nisha (Simi) who, we learn as the spools unravel, was born with a golden spoon but propagates socialism.
On reaching home, Vicky meditates over Somu's (Rajesh Khanna) garlanded photograph. It does not leave you with much guess work about his character's culmination, but it is the perfect cue for a flashback.
