Lights Out

“You were right to be afraid of the dark.”

Rebecca (Teresa Palmer) and her young half-brother Martin (Gabriel Bateman) discover that a malevolent spirit from their family's past emerges only in darkness, killing anyone it finds. The entity haunts their mother Sophie (Maria Bello), and now it's hunting them too. They must stay in the light or die, but eventually the sun sets, the power fails, and there's nowhere left to run.
