Liz Waid is a sleeper CIA agent in Belgrade, Serbia still reeling from the recent loss of her son. When a military satellite crash lands somewhere in Serbia, she is part of the team dispatched to secure the remains. By the time they arrive on-site, however, the satellite has vanished. Liz and the team initially ignore the local villagers when they say an extraterrestrial entity came from the sky along with the satellite – but then the dead begin to rise. As their time runs out, the team must battle evil forces to unlock the terrifying truth behind the ill-fated mission.
