R&R

A diner worker named Ralph befriends a quiet regular named Riger, believing she's a harmless alien unfairly hunted by authorities. When she begs him for help escaping, he secretly drives her deep into the woods-only to discover she's the captain of a predatory species using illusions to lure humans as food. As her crew captures dozens of people, the detective who had warned Ralph arrives with allied "smog breather" aliens, revealing they'd been tracking him to stop the invasion.
A battle erupts, Riger's true monstrous form is exposed, and her species is wiped out, leaving Ralph shaken as the star of her homeworld disappears from the sky.
