Mark, a tough-as-nails LAPD detective, struggles to mend his relationship with his estranged son, Trent, following the death of his wife. During a subway ride, their city is suddenly attacked by an alien invasion. As pandemonium ensues, Mark and Trent, along with a small group of survivors, are ensnared by a colossal alien spacecraft that begins to vacuum people up. Inside the ship, they witness humans being harvested for their brains to power alien bio-mechanical soldiers. Mark, determined to protect his son, allies with Audrey, another survivor and medical doctor. Together, they mount an escape plan from the ship's nightmarish interior.

They manage to escape and crash-land in the jungles of Laos, where they encounter a tribe led by a skilled fighter named Sua. Here, the survivors find a temporary haven but also learn of the larger stakes at play—the aliens' plans for global conquest and terraforming Earth. As tensions mount and the aliens draw closer, Mark must navigate both external threats and internal conflicts within the group to safeguard humanity's last hope for survival. The survivors’ resolve is tested as they prepare for an all-out battle against their extraterrestrial adversaries.
