Trigger Fingers plot
Marshal 'Lightning' Bill Carson and his partners Magpie and Margaret attempt to capture a gang of cattle thieves. The only clue is a saddle with the fingerprints of one of the thieves on it. To solve the case, the three dress up as gypsies and Bill will predict the future to the interested via playing cards. Afterwards they can check the playing cards for the correct fingerprints. Unfortunately, the three find no clues, but inadvertently end up at the gang's hideout. Gang leader Lee soon realizes them, however, and the three get into trouble.
