Adelaide Wilson and her family embark on a summer vacation to Santa Cruz, where unsettling memories from Adelaide's childhood trauma at a funhouse resurface. Her apprehension grows into a chilling reality when a doppelgänger family, dressed in red jumpsuits, materializes in their driveway, forcing their way into the home. These doppelgängers, known as the Tethered, are exact replicas of Adelaide, her husband Gabe, daughter Zora, and son Jason, but with malevolent intentions and a mysterious connection to their counterparts. As the Wilsons fight for survival against their twisted look-alikes, they discover that this invasion is not isolated; an army of Tethered has risen across the nation, emerging from subterranean tunnels and seeking to replace their surface-dwelling counterparts in a violent uprising. Adelaide realizes her own Tethered, Red, is the leader and harbors a personal vendetta, leading to a brutal confrontation that reveals a shocking secret: Adelaide herself is one of the Tethered, having swapped places with the original surface Adelaide in the funhouse many years ago, and Red is the real surface Adelaide, now orchestrating this rebellion from below.
