The Fighting Buckaroo (movie, 1943)

In this western, a lonesome cowpoke trots into a town and helps clear his pardner's name. The trouble began when the friend was framed by the leader of the Cattlemen's association who made it seem like he was a rustler. Because the friend was an ex-con, the evidence against him seems airtight. The wandering hero must work extra hard to prove his friend's innocence.
