At a motel in the outskirts of the city a car is parked in such a way that it obstructs others driving out. The watchman is alerted and very soon they all hear the a ticking sound as if a bomb is about to go off. CID is called in and so is the bomb disposal squad. Surprisingly, a dead body of a woman is recovered from the trunk which is a few days old. Forensics find that inside her ear are some eggs of a rare butterfly. CID gets cracking on the case with this slender evidence.
