After a U.S. weapons test off Australia's coast caused an EMP pulse that killed half a million, the horror was compounded by a fraction of the stricken returning to life as passive automatons. American Ava (Daisy Ridley), whose husband (Matt Whelan) was in country, signed on for the volunteer cleanup effort-but her bid to find him and closure will turn terrifying as the "reboots" prove less benign than first believed. Thoughtful genre spin from Down Under co-stars Brenton Thwaites, Mark Coles Smith. 94 min. Widescreen; Soundtrack: English.
