Balabhaskaran (Jayaram) suffers from sleepwalking. He walks long distances in the night and many mishaps happen because of this. He is blamed for a murder by his friend Johnnie (Madhupal), who wants to extort some money from Balabhaskaran by blackmailing him. Balabhaskaran's father marries him off to Chandrika in the hope that this will help him to get over his sleepwalking.
