SLUMBER PARTY MASSACRE PART 2 1987
Crystal Bernard "stars" as a teenage girl re-traumatized by a killer from her past. It does indeed take place at a sleepover at a "condo" owned by a band member's father.
I'm going to have to watch SPM part 1 to see the killer's back story (if there is one...)
Nothing really great about it except that I enjoyed it.
