Reading about a young man in Kansas who has gained a reputation as the movies' number one fan, Harris summons him, Joe Ruddy, to ask his advice about a new gangster story.
Molly manages to coax her brother into doing the movie, eager to get him to give up his criminal ways and even hiding a million dollars of his cash until he turns over a new leaf.
On the movie set, leading lady Vera Valaize is irate about the casting and Buggsie's rewriting of the scenes, so she walks off.
By the time Buggsie straightens everything out, he finds out Molly's fallen in love with Joe and arranges their wedding on the way home.
