Return of the Seven (1966)

Fifty gunmen force all of the men in a small Mexican village to ride off with them into the desert. Among the captured farmers is Chico, who years before was one of seven hired gunslingers responsible for ridding the village of a tyrannical bandit, Calvera. Chico's wife, Petra, seeks out the other members of the band of whom only two, Chris and Vin, survive. She begs them to save the village once more. To replace the deceased members of the group, Chris buys the release of Frank and Luis, held in the local jail, and also recruits Colbee, a ladies' man and deadly gunman, and Manuel, a young cockfighter.

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 force Lorca's men to leave, and, with Chico, prepare for a counterattack. The cowed farmers offer no assistance, but the seven defenders successfully repulse Lorca's initial attack. The rancher then gathers all of the men on his land to rout the seven.

The situation seems bleak until Manuel discovers a supply of dynamite which the seven use in a counteroffensive. They are eventually overrun, but Chris emerges victorious from a shootout with Lorca. The rancher's gang flee, leaving Frank, Luis, and Manuel dead in the fighting. Chico plans to resettle the village on Lorca's fertile land, and Colbee remains to help teach the villagers how to defend themselves against future attacks - and pursue the available women. Chris and Vin once more ride off as the church bell rings seven times.
