Alex heads to Edwards Island for a weekend party, traveling with Ren and Jonas. The trio settles into the island vibe and begins to anticipate a carefree time away from home. The weekend promises mischief and the lure of something strange lurking just beneath the surface.

On the island, they meet Clarissa, the ex girlfriend of Alex's late brother Michael, and Nona, Clarissa's friend who is also Ren's love interest. Ren explains the island's history as a former military base and mentions Maggie Adler, the island's lone permanent resident who has just died. The group senses there is more to Edwards Island than a simple weekend party.

They camp on the beach and explore the network of nearby caves. Rumors say radio frequencies in the caves can spark strange, otherworldly happenings.

In a small cavern, Alex twists the radio toward a floating shape and unexpectedly activates a dimensional rift. A voice answers, and the teens begin to experience vivid visions before collapsing.

When they awaken, Alex and Jonas find themselves in front of a communications tower somewhere else on the island, while Ren collapses in the woods and Clarissa reaches them from a decommissioned military fort. The split begins to reveal that the island's spaces are connected by the rift.

The woods are filled with inexplicable phenomena: Alex's own reflection speaks to her from the water, objects move on their own, and time begins to loop. The loops reset when Alex plays a reel-to-reel tape, hinting that memory and rhythm anchor their reality.

Nona asserts she has seen an alternate version of Jonas and Alex during one of the loops, heightening the mystery. The search for Ren continues as the friends try to understand the looping world they're trapped in.

They locate Ren, but a later loop shows him possessed by a spectral ghost. Alex uses the radio to open another rift, which returns Ren to normal and allows the group to retreat to the tower to regroup.

Inside the military fort, Alex's reflection inexplicably appears in a mirror and begins offering guidance, while a ghost questions their purpose and briefly possesses Jonas. The haunting reveals that the ghosts are the crew of a submarine, the USS Kanaloa, presumed lost at sea, and that the threat remains.

The search for Clarissa leads to a disturbing turn: after a time loop, Clarissa leaps from a ledge and vanishes again as the loop resets. The four friends return to Harden Tower and realize they cannot broadcast a signal off the island yet, so Ren proposes a desperate plan to reach Maggie Adler's estate and use a boat to pierce the veil.

At Adler's estate, a possessed Clarissa speaks with Alex, while letters left by Adler hint at a deeper history. The letters reveal Adler and her confidant Anna had tried to communicate with the Kanaloa crew via radio, but Anna was dragged into the rift. They also imply the Kanaloa crew were pulled into another dimension because of the submarine's experimental nuclear reactor, not enemy fire.

With this knowledge, the group sets out to repair the rifts by crossing to the other side and tuning the radio from within. The story loops back into time as Alex repeatedly returns to moments she shared with Michael, searching for a way to fix what happened.

In a tense moment, a ghost possesses Jonas and offers a bargain: spare Alex and the others if they leave Clarissa behind. The group faces an impossible choice as the rift's power intensifies.

Back in the caves, Alex tunes the radio toward a rift that drives her into a void, where she encounters the possessed Clarissa and hears dire warnings from the ghosts. The ghosts warn that closing the rift may doom Clarissa, while leaving through the rift could cause her to disappear, forcing a crucial decision.

When Alex awakens again, she finds herself back with Ren, Jonas, Nona, and Clarissa on the ferry home. Jonas confirms that whatever they did has mended the rift for now, and the friends vow to keep what happened a secret, sealing the moment with a quiet group photo.
