In the near future the world's food supply has been decimated by a plague. Nothing grows. On the streets of New York City various groups fight for survival. Most are barbarians and cannibals, but one group, who lives on the rooftops, is more civilized. It's this group, led by a character called 'The Baron' (Max Von Sydow) that has discovered how to breed a crop of plague-resistant plants. Fearing that one of the other groups will take them over, they recruit a warrior (Yul Brynner) to protect them. When things start falling apart the Baron convinces the warrior to take his pregnant daughter to the safety of an island that's down South--but before he can do that he has a showdown with the evil gang's leader (William Smith). One of the better post-apocalyptic movies from the 70's.
