Everybody's welcome at Ma's. But good luck getting home safe. From the acclaimed director of The Help and blockbuster producer Jason Blum comes a thriller anchored by a daring and unexpected performance from Oscar-winner Octavia Spencer. A loner in a quiet Ohio town opens her basement to a group of teens, providing them with a safe place to party and prevent them from drink driving. But when the kids break Ma's house rules and her hospitality curdles into obsession, the teenage dream becomes a nightmare.
