Three Bad Sisters - 1956 - 5/10

Wealthy father dies in a plane crash (while the pilot miraculously survives).
Three daughters stand to inherit a three-way split.
Or … if one dies, a two-way. Or … if another, mine all mine!
One sister is goody-two-shoes, meaning Dullsville.
The other flirts, goes shopping, runs around. Yeah, lively and rambunctious, the fun date.
Sister number three, though, Valerie, whoo boy. Poster child for devious psychopath.

Would that the other two, Vicki and Lorna, were in her league.
Then, this might be a must-see exploitation gem. As is, Valerie is the flame to watch.
