When a happily married Alby is confronted by his old love for help, things go wrong and a string of serial murders form the rest of the plot.

Alby (Nishan) works in a Nissan showroom. His wife, Ann (Mridula), works as a Radio Jockey. Alby's old sweetheart, Nimmy (Shritha) enters his life when she is deserted by her husband, Vishnu (Kailash), after he suspects her of an affair. Alby is forced to take her to a homestay, where they share a room together. The story takes a sudden turn when Nimmy is found dead. Alby tries to move on with his life until he is disturbed by a call from a stranger at 10:30 AM local time. He is extorted into doing the commands of the caller, and finds himself disturbed doing those works.—Salman Arif Mahmud
