After the nuclear war the fight for survival begins.

Survival Zone (1983)

Directed by Percival Rubens

In a post-nuclear world, a happy family of ranchers is beseiged by a roving band of ne'er do well marauders who want to eat the men and mate with the women. Having already killed and eaten an entire mission full of nuns, the family has no choice but to grab their rifles and defend their homestead. Meanwhile, the lonely, nubile daughter begins to have feelings for the buff blond stranger with no family who has wandered onto the property. It's romance, intrigue, action, and violence on the dark continent!
