No One Will Save You 

A roundup

Brynn, a young woman living alone in her childhood home, is awakened by an alien intruder.

Brynn tries to escape, but the alien uses telekinesis to subdue her.

Brynn accidentally stabs the alien in the head, causing it to release her.

The aliens take Brynn to their ship, but they decide to spare her and return her to Earth.

Brynn discovers that the aliens have taken over the town, but she is allowed to live freely in her home.

In the end, it is unclear whether Brynn has joined the alien society or whether she is simply being tolerated. The film is ambiguous and open to interpretation.
