A department pariah since he rolled over on a corrupt partner a decade earlier, detective Zeke Banks (Chris Rock) got saddled with a grisly subway murder-and he'd discover the perpetrator to be a copycat of the infamous Jigsaw. As the body count grew, he'd discover the victims' stunning linkage-and have to figure out how to end the carnage. Anticipated "Saw" spin-off co-stars Samuel L. Jackson, Max Minghella, Marisol Nichols; director Darren Lynn Bousman makes his franchise return. 93 min. Widescreen; Soundtrack: English.
