Ver Cuevana2. A handsome but penniless young man takes a summer job as a swimming instructor in a picturesque Alpine lake resort. He falls in love with a young heiress who is staying there with her father, but he also grabs the attention of tomboyish Puck who lives on the other side of the lake and who saves him from drowning one foggy night. Further havoc is caused by the arrival of Eric's old sweetheart whose husband is wanted by the police.
