The six men discover that the missing villagers are being used as slave labor to rebuild a desert village and church as a memorial to the dead sons of wealthy rancher Lorca. In a surprise attack, the six gunmen force Lorca's men to leave, and prepare for a counterattack with Chico. The cowed farmers offer no assistance, but the seven defenders successfully repulse Lorca's initial attack. Lorca, the rancher, then gathers all of the men on his land to rout the seven men.
