The trailer leans into a mix of psychological tension and sci-fi mystery as the characters struggle with isolation, fear, and the creeping suspicion that something inside the bunker might be just as dangerous as the alien ships outside.

Alongside Edmundson, the cast includes Chad Michael Collins, Christopher Matthew Cook, Cullen Douglas, Debbie Fan, and Sharif Ibrahim. Horror icon Tobin Bell also appears in the film, and the cast features one of the final performances from the legendary Tony Todd, who plays Frank Lawrence, an army commander working with the White House.
