Alien Raiders

A group of six armed, masked individuals infiltrate a local grocery store just before closing time. They take staff and remaining customers hostage, shooting down one employee immediately. Spooky, one of the masked men, is tasked with checking if any hostages are infected, setting the tone for the tense confrontation.

Spooky attempts to identify infected hostages among the captives but is interrupted when he recognizes a woman as 'one of them' and she tries to escape, resulting in her being shot. Meanwhile, a police officer inside the store manages to kill one of the masked intruders, but is soon shot and killed himself.

Upon police arrival, the armed group debates whether to continue or abort their mission. Ritter, their leader, insists on finishing their plan, and the group releases the hostages Spooky had already cleared, moving the others to the back of the store. Tensions rise as they inspect a corpse revealing infection.

Discovering the corpse was infected, the group switches from checking hostages with fingers to a more brutal method—cutting off fingers to test for the organism. Doctor Sterling performs these tests on hostages, escalating the group's desperation and paranoia.

Outside, Seth, a policeman whose stepdaughter Whitney works at the store, takes charge. They learn Ritter was formerly a rocket scientist and that the group is hunting parasites brought to Earth by a meteorite. Negotiations begin, with the promise of one hostage release in exchange for Charlotte, a group member with special abilities.

Inside, the group discovers another woman is infected, and they kill her, heightening the tension. Suddenly, the revitalized police officer, now possessed by an organism, attacks and kills several captors and hostages, creating chaos within the store.

Ritter explains to the remaining hostages that the parasites are divided into groups, with a single king parasite being crucial for their survival. They believe one person inside the store carries the king, making everyone else a potential host for extinction.

Seth and Charlotte enter the store. With Charlotte’s help, the group sets a trap to lure the infected cop while Seth evacuates Whitney and Benny, who volunteers to have his finger cut off to keep Whitney safe. The tense strategy aims to eliminate the parasite presence.

Ritter successfully cuts the living parasite from the infected cop, neutralizing the threat momentarily. However, police open fire, gunning down Ritter before he can destroy the parasite completely, intensifying the final confrontation.

Sterling is arrested while Charlotte realizes that the parasite Ritter removed was not the king. In the police car, Benny overhears Seth revealing that Benny himself might be the king. The realization dawns that Whitney, not checked earlier, could be the true host.

Benny aims at Whitney as her eyes and veins darken, revealing her as the true host of the king parasite. The scene fades to black while Benny screams, signaling a catastrophic turn and unresolved tension about who will survive the ordeal.
