The professors' wife lives as abused mentally by her husband. One day the couple goes climbing with a young man, who works for a pharmaceutical company and often visits them on business. While they scales a cliff holding a rope, her husband under them loses his footing and falls down. When they all are about to fall, she cut the rope, so the husband died in a fall. She stands at the bar, but the court decides the case is an emergency evacuation. So she obtains an acquittal, but murderous intent in her mind must work on her.
