Geeky teenager David and his popular twin sister, Jennifer, get sucked into the black-and-white world of a 1950s TV sitcom called "Pleasantville," and find a world where everything is peachy keen all the time. But when Jennifer's modern attitude disrupts Pleasantville's peaceful but boring routine, she literally brings color into its life.

The tranquility of a small town is marred only by sheriff Tod Shaw's unsuccessful courtship of widow Ellen Benson, a pacifist who can't abide guns and those who use them. But violence descends on Ellen's household willy-nilly when the U.S. President passes through town... and slightly psycho hired assassin John Baron finds the Benson home ideal for an ambush.
