In Charlie Chaplin's fifth Keystone comedy we get a look inside the famous laugh factory. Charlie is a movie fan and we first see him creating havoc at a theatre where he gets too involved with the action on the screen and the beautiful actress in the film. Ejected from the theatre, he proceeds to Keystone itself where he mooches money from Roscoe Arbuckle as he arrives at work. Charlie sneaks into the studio and disrupts the filming, much to the chagrin of the director. He mistakes a scene where the starlet is being manhandled for reality and comes to her rescue. Firing a prop pistol in all directions, he clears the stages before leaving. Meanwhile, a Keystone scout sees a building on fire in a nearby street and telephones the studio. In a parody of Mack Sennett's propensity to use public events and disasters as backdrops for his films, the cast and crew rush off to do some location filming at the fire. Charlie shows up and again disrupts the filming, causing the director to take after him brandishing a club. The firemen arrive and seeing the struggle between the director and his assistants who are trying to restrain him, turn the hoses on the fighting men. Charlie again tries his luck with the beautiful actress and receives a good shaking in response, followed by a soaking by the fire squad. In a classic Chaplin move, he twists his ear as water squirts from his mouth. When the beautiful actress laughs at his condition, a water-logged Charlie gives up on his movie fanaticism.
