4K UHD - With its Christmas lights and dusting of snow, Kingston Falls is an idyllic small town - until the gremlins take over. A father returns from Chinatown with an unusual pet, a Mogwai - a gift for his son. The rules are simple: keep your Mogwai away from water, bright lights, and, most importantly, never - never - feed him after midnight. But the rules are inadvertently broken, and the consequences multiply at an alarming rate.
