Dan the boaster wins Anita away from Adrian, her devoted sweetheart. Wandering disconsolate on the sands, Adrian overhears the beach life guard telling an admiring bevy of bathing beauties stories of his bravery in winning many medals. Adrian consults the good-natured guard on how to be a hero. Larry gives the youngster lessons in how to deport himself so he can make the biggest hit with the little girls, covers his little bathing-suit with medals, and sends him back to recover his lost love. Dan and Adrian come to blows over their respective claims to bravery, and Anita, thinking to test the mettle of the rivals, pretends to be drowning, but she ventures out too far and finds herself sinking in earnest. Adrian, determined to live up to his medals and his ideal of heroism, dares all to save Anita. The two children are swept far out by the surf, and are rescued by Larry, the life guard.
