3 of the daughters were killed by Freddy Krueger
The main thing I remember about this show is that 3 of the 4 teenaged daughters were in Nightmare on Elm Street movies:
Heather Langenkamp was in Part 1 and 3
Brooke Theiss was in Part 4
Jo Ann WIllette was in Part 2
...and they say horror actresses can't get work!
