Dumb but honest insurance agent Henry Twinkle (Lew Ayres) is in love with Mary Blake (Rita Johnson), the secretary of Henry's boss. To impress Mary, Henry sells a huge policy to wealthy Gus Fender (Lloyd Nolan), who turns out to be a notorious gangster on the lam from the law. If he wants to save his job, Henry will have to protect Fender from being killed. After a series of hair-raising adventures, hapless Henry ends up collecting the reward money for Fender's capture, only to be duped into turning it all over to the gangster for bail money. Saving Henry's hide-and his relationship with Mary-is a share of seemingly worthless stock which unexpectedly pays off big-time.
