Jean Kelly, a reporter, is outside the seashore home of Lynn Morril when a burglar enters. Scenting a story, she waits. Morril surprises the burglar, notes that the man resembles him, and changes places with him, for his aunt and cousin, Lillian, whom he dislikes, are coming on a visit. The new watchman fires a shot at Morril and he flees, dragging Jean with him. Hard pressed, he boards his motorboat. The girl jumps overboard and he tries to rescue her. They are cast upon a small island, from which they later escape on a raft. Reaching home, they find the masquerading burglar in disgrace. He makes a quick exit, and Lynn introduces his fiancée to the guests.
