Mabel Normand and her sweetheart go to the beach and play a trick on the boyfriend's father.
Normand performed her own diving stunts for this film, which was the first Keystone comedy. Notably, the film precedes, and may have been the direct inspiration for, the Sennett Bathing Beauties performers first featured in 1915. The connection is rather obvious, of course.
This is another early showcase for Normand, who really ought to be seen on the same level as Chaplin, Lloyd and Keaton. Arguably she did not make the impact they did, but one would be hard-pressed to think of any female comedian of her era who stood out nearly as much.
