When Meera Mujumdar is off watching a play with an old flame, her husband, Niranjan, puts in place a grand plan to murder her. The plan is foolproof, the alibis are plotted and provided for, and the date is set.
On a rainy night, Meera sleeps alone in her house. At the designated time, the telephone rings. As Meera gets up to answer it, she has no idea of the dark shadow that lurks behind her drapes.
Will Meera somehow escape from her predicament? Or will Niranjan get away committing, 'A PERFECT MURDER'?
