A family's serene beach vacation turns to chaos when their doppelgängers appear and begin to terrorize them.
When Addie and Zora are talking in her room earlier in the film, one of the books on Zora's end table is entitled "They Came From Below", which foreshadows the arrival of the Tethered from the underground tunnels.
They look exactly like us. They think like us. They know where we are. We need to move and keep moving. They won't stop until they kill us... or we kill them.
After Abraham tries on Gabe's glasses, he takes them off but we never see Gabe get them back. Gabe is wearing them in the next scene.
The names of the Tethered are colored red in the credits.
