Tom Mathison is David, a young man who finds out from fellow teen campers that his father was not a hero who died in combat in Korea, but rather a gangster. He angrily runs away to a nearby family cabin, and armed with rifle, threatens to shoot anyone who approaches. Ted (Larry Pennell) and Jim (Ken Curtis) agree to help by skydiving to the cabin, but David's father "Doctor" Partlow (Grant Richards) shows up and wants to go after David by himself, warning that he will shoot anyone who tries to interfere.
