Plot.
Borgohain, a journalist of repute, was traveling to the countryside for a break. When his car breaks down in the middle of a rainy night, a nearby mechanic comes to fix it. Learning his identity, the mechanic has a request of his own. He has been pining for a beautiful maid, who had accompanied a film unit during shooting at the countryside. She was a personal helper to a leading actress, who incidentally has vanished from the film industry. 
Borgohain agrees to look for her out of curiosity. More of a love story than a traditional mystery, his investigation takes him across the world of show business and make believe people.
