Olly, the lighthouse keeper’s daughter, is persuaded by her father to accept the attentions of Joe, a fisherman, whom she dislikes. Dick Mathews arrives at the seashore with his mother to spend his vacation and calls at the lighthouse in view of renting a boat for a daily row. He meets Olly and it is a case of love at first sight. They are seen quite frequently together by Joe. The seed of vengeance now sprouts in his heart, and being cognizant of Dick taking a daily row, saws the oars partly in half in the hopes that Dick would row out to sea, the oars break, and that he would perish. It occurs, however, that Olly, deciding to play a joke on Dick, takes out the boat. When out quite a distance the oars break and she is tossed around by the waves. Dick goes down to where his boat is kept, followed from behind by Joe, who is anxious to see his plans fulfilled, but is surprised to see that his boat is gone. He finds Olly’s bonnet, and, thinking that she has played a joke, passes on. Joe is horrified to see the boat gone, and on finding Olly’s bonnet, it occurs to him instantly that the fate he prepared for Dick has befallen Olly, and he rushes to her father, stating that Olly must have drifted into the sea. The father rushes down to the sea, followed by Joe, and they start a search, Joe in a boat, the father searching the shore. Dick, on looking from a rocky elevation overlooking the sea, spies Olly frantically waving her apron in the drifting boat, and with the aid of two fishermen, rows out and rescues her just as she collapses from exhaustion. The sea becomes very rough and Joe’s boat is wrecked and he swims to a reef, where he finds the wreck of Olly’s boat. He becomes remorse-stricken, but he realizes that he is doomed. The nest morning Olly is taken to her father, whom she tells of Joe’s dastardly attempt to kill Dick. The father, wild with rage, rushes out to search for Joe. He finds Joe’s body washed ashore and proceeds to denounce him, but sees that he is dead.
