Plot: Mickey, Jack and the gang are waging a war near the location of West Coast Studios with old vegetables against Toughy and his army. Mary is playing the role of a Red Cross nurse they keep going to with battle injuries. Farina is more obsessed with capturing a skunk as a pet. However, Mary is soon called away in her role as a young actress at the studio, and the gang instead tries to follow her into the studio, but they are chased away by the guard. Farina has no problem sneaking in and the rest find entry in following him. The guard chases them through indoor and exterior sets, disrupting various movies being filmed. They find Mary on the set of "Should Husbands Work?", seemingly being "strangled" by an older actor and rush to her rescue, bringing the scene to an end as the director cuts for lunch. The gang decides to create their own movie in his absence with the same set and camera, both exposing and double-exposing the existing footage. After watching the altered film in horror, the director joins the guard in chasing them out of the studio. Harold Lloyd helps their escape by disguising them as Mexican refugees in sombreros. By now, Farina has caught the skunk, driving off the gang even further.
