Skull Rating: 3
When Tonya (Ailsa Marshall) finds herself stranded in an unfamiliar room with 13 prisoners, and each is held hostage by an electronic collar left to agonize about what horrible fate may await. It turns out, they’re slated to die, and as the clock ticks down, the terrified strangers go toes up one by one. The catch, of course, is that one of them is the killer — but who is it?
Rated R, 1 hr. 29 min., 2007
There a few movies like this where you have a single location and we a forced to examine each character to figure out the puzzle. This one is good and I would recommend it.
