When old rancher Cordoba's grandson is murdered, the Cisco Kid takes his place to find who's trying to take over the ranch.

Phoebe Titus is a tough, swaggering pioneer woman, but her ways become decidedly more feminine when she falls for California bound Peter Muncie. But Peter won't be distracted from his journey and Phoebe is left alone and plenty busy with villains Jefferson Carteret and Lazarus Ward plotting at every turn to destroy her freighting company. She has not seen the last of Peter, however.
