A county detention center becomes the last line of defense in Attack of the Unknown, a 2020 American action-horror hybrid from director Brandon Slagle that drops an alien invasion straight into the middle of a prisoner transfer.
What is Attack of the Unknown about?
The setup starts small: a SWAT unit is moving a dangerous crime-syndicate boss between facilities when the outside world abruptly stops making sense. A catastrophic invasion by unidentified attackers turns the transfer into a siege, trapping the officers, their prisoner, and everyone else inside the detention center as the situation outside deteriorates. With extraction off the table, the group has to decide whether survival means holding position or fighting their way out through hostile territory. The film leans into genre staples, a confined setting, an antagonist who might be more useful alive than dead, and a threat nobody inside the building fully understands, and uses that claustrophobia to keep the pressure on scene after scene. Science-fiction elements sit alongside straightforward action and horror beats rather than dominating the film, keeping the focus on the trapped ensemble rather than on the invaders themselves.

Context & significance
Attack of the Unknown is a 2020 American production that mixes action, horror, science fiction and thriller elements into one compact package. Its premise borrows from siege thrillers and creature-invasion features alike, using a detention center's isolation as both a practical setting and a way to raise the stakes of an already dangerous prisoner transport. Genre fans looking for a fast-moving mashup rather than a slow-burn drama are the natural audience here.
