The body of a doctor is found floating in a lake by a claims man and his two young sons. The investigator's company had written a large insurance policy on him a year before which stated that if he committed suicide within two years, the company could deny payment. The case was assigned to the young claims man to clear up the mystery and this took him on a long and complicated journey. He uncovered a witness who lived in a cave that overlooked the river where he went in. With the help of the hermit, he was able to solve the mystery.
