The U.S. Secret Service goes after a counterfeiting ring by placing one of its agents in a criminal mob.

The ambitious son of an accomplished race driver struggles to outrun his father's legacy and achieve his own successes.

Daring Cabellero was the third of producer Phil Krasne's Cisco Kid "B" westerns. Duncan Renaldo and Leo Carrillo return as Cisco and Pancho, roles they'd carry over into a popular 1950s TV series. Once more stumbling into a dangerous situation, Cisco and Pancho risk their own necks by saving an innocent man from hanging. Eventually, our heroes learn that a corrupt political machine is behind the killing. Leading lady Kippie Valez is cast as "herself," which must have meant more in 1949 than it does today. Unlike the subsequent TV series, Daring Caballero does not end with the leading actors reciting their standard mantra "Oh, Pancho! Oh, Cisco!"

When that success leads Foster to run for governor, Beal's unearthly hold on him turns the previously honest man corrupt, much to the displeasure of his wife and his steadfast minister.
