Having broken the time loop that saw her slain on her birthday over and over, Tree Gelbman (Jessica Rothe) discovered that her peril stemmed from the quantum experiments of classmate Ryan (Phi Vu). His efforts to clean up the mess only succeed in thrusting her into a parallel universe with some key differences-including, unfortunately, that the Baby Mask Killer's still out there. Israel Broussard, Ruby Modine, Rachel Matthews, Charles Aitken also return for this diabolical do-over. 100 min. Widescreen; Soundtrack: English.
