Given an hour off from his job as a cafe waiter, Charlie rescues Mabel from a thug, is given an invitation to her home, and arrives presenting a card which falsely identifies him as the Greek Ambassador. Before he can get back to work, her parents invite him to a future garden party. Her jealous lover has Charlie followed back to the cafe. Charlie is a hit at the garden party but, as he leaves to return to work, the rival invites everyone to go with him to the cafe so Charlie will be exposed.

Charlie pretends to be a dentist though he is only his assistant. When a patient can't stop laughing from the anesthesia Charlie knocks him out with a club. He is sent to the drug store, gets in a fight with a man who (after a brick in the face) becomes another patient, and pulls the skirt off the dentist's wife (who is out walking). At one point Charlie pulls a tooth (the wrong one) using enormous pliers.

When a married couple become separated in the park, Charlie takes up with the lady and is beat up when her husband rejoins her. He takes a room in their hotel, and she sleepwalks into his room so that when her husband returns from his walk he must go out again to look for her. Charlie returns the lady to her room but must climb out onto the window ledge in a downpour.
