Epitaph(1988)

“Yes, Mother. I've done my homework, cleaned my room, & buried Dad!”

It seems the Fulton family has to keep moving from one town to another, because the mother is a homicidal maniac who murders any man who doesn't submit to her drunken seductions. And Mr. Fulton, like any good, caring husband, never thinks twice about burying her victims in the backyard, packing up the family car, and setting off for a brand-new destination.
