Sometimes you can find true quality b-movies like this one. The brevity makes all of the plot twists and turns seem more exciting, and the unfamiliar stars make their actions all the more ambiguous which makes the ending harder to predict.
Baseball player Tommy "Mr. Dynamite" Thornton (Lloyd Nolan) finds himself wrapped up in a murder case when he follows a pretty girl (Irene Hervey) into a Coney Island vaudeville theater who winds up to be sitting next to a murdered man. Vicki claims to be innocent, but lies to Dynamite about her reasons for ducking into the theater. She changes her tune when the cops start to follow her and other more dangerous characters make their presence known. The two enlist the help of baseball fanatic Joey (Ann Gillis) and her eccentric friend the Professor (J. Carrol Naish) to solve the murder and to keep out of jail. Shemp Howard makes an appearance as a phony fortune teller.
The mystery is played out excitingly with plenty of twists and turns, but not too many as to confuse the audience. The actors are all very competent and fun to watch.
