The Magnificent Seven (1960)

When their small village is once again attacked by the bandit Calvera, three Mexican farmers head north to try to buy guns. They ask Chris Adams to help them, but he suggests they hire experienced gunmen instead. He soon recruits five others and eventually accepts a sixth he had initially rejected, but who made saying no impossible for him. Together, they develop a plan to secure the town and defend it against Calvera's attack. In that time, friendships are formed and love blossoms between one of the men and a beautiful local girl, but not all of them will survive the attack.
