In an effort to prevent a terrorist attack on Washington D.C., an elite squad of Navy SEALs led by Lt. Blake Harris (Scott Adkins) and a junior CIA analyst Zoe Anderson (Ashley Greene) must retrieve a prisoner from a CIA black site island prison. Tensions flare as Deputy Site Manager Tom Shields (Ryan Phillippe) refuses to release the suspected terrorist based solely on Anderson's intel, but when the base comes under attack by waves of insurgents they must band together to complete the mission.
