Ruth Wilson, daughter of a wealthy landowner, receives a visit from her country sweetheart, Joe Merriam. who is a motorboat enthusiast. Unknown to anyone but her brother Frank, Ruth is an expert at fixing auto and motorboat engines as the estate is on the bay and Ruth has the use of two launches. With Joe she goes for a boat ride but the engine breaks down and he is unable to fix it, and afraid that it would lower his opinion of her if she should repair the engine, she lets him call another boat to tow them back to the wharf. Merriam, while in love with Ruth, cannot bring himself to propose, fearing that she would be too ornamental for a farmer's wife, and half of his visit passes while he attempts to make up his mind.
