Prison Shadows

Plot summary

Gene Harris, a prizefighter, is sentenced to five years in prison after killing an opponent in the ring. Gene's trainer Moran is suspicious of promoter George Miller, whose accomplice Claire Thomas is pretending to be in love with Gene while double-crossing him.

Gene is paroled after three years. He returns to boxing, supported by Mary Comstock, a girl from Miller's office who believes in Gene's innocence, even after another foe dies while fighting him. They discover that an undetectable poison is being used on the fighters' towels. Overhearing a plot to kill him the same way, Gene plays dead and is carried out, setting a trap with the police that the villains fall into right after the fight.
