The movie marked Sadhana's comeback after a brief period of illness during which she lost movies like Sangharsh and Around the World. Here she plays a working girl Rita, who is falsely implicated by her employer Sohanlal (Rehman) on theft charges. During her year long imprisonment, her mother dies of starvation and she in turn swears revenge. (Hence the title). She saves a smuggler,Ashok Kumar from jail and both get rich by selling the diamonds which he was to smuggle. They set up a casino and Rita works towards ensnaring the young Rajpal (a very stiff Sanjay Khan), Sohanlal's son. They get married against his father's wishes and Rita starts showing her true colors et. all. Towards the end, Sohanlal realizes his folly and apologizes to Rita.
The movie had some fantastic music courtesy Laxmikant Pyarelal. There is also one of the most erotic cabaret number ever picturised on the lovely Helen.
