Cruise stars as Ray Ferrier, a divorced dockworker and nowhere-near-perfect father. Babysitting his kids after his ex-wife drops them off at his place for the weekend, hell literally breaks loose as a freakish, overwhelming lightning storm crashes around them.

Their life changes forever. And Ray begins to wage a mad battle to save the ones he cares about.

'The question is,' says Cruise, 'are they going to make it? Will they survive? And to what extent will you go to protect your children?'
