 A man is on the ledge in a high building, ready to jump. There are efforts to get him back in. The gaping passers by are there, an irate police inspector, and people who s work is disturbed as well as other who are mistakenly called in as jumper s parents or his fiancée. A retired psychology professor who is in conflict with a brilliant ex- student is also trying to help. The old man is the only one who can get to the man on the ledge and finally talks him in after confessing a suicide attempt of his own.
