Four spirited young friends travel to a remote summer lodge eager for outdoor fun and to welcome their boyhood friends home from the war. A joyride turns dangerous when their car fails, and their visit unfolds into a sequence of suspenseful incidents including encounters with an isolated hermit, strange moonlit apparitions, a daring hold-up, a perilous whirlpool, illness and an apparent tragedy, culminating in a revealing resolution that restores the group and returns life to its former camaraderie.
