Dennis O'Hara is a poverty-stricken Irishman who believes that if he comes to America he will immediately land a job as a policeman. So he manages to scrape together the funds to get him to Manhattan, and leaves his sweetheart Katie O'Grady behind while he makes his fortune. Naturally he discovers that joining the force isn't as easy as he expected, and when he does finally get in, he winds up in trouble because of the graft collections of his boss.

The story has been adapted from the Sir Arthur Wing Pinero play. The title means nothing more than the mid-channel of married life, through a character in the feature likening the roughness of the English channel in the center of the trip across from London to Paris to the woes married folks meet in their wedded life.
