In July 1994, ten-year-old Ethan Marsh and his best friend Billy Barringer lead a group of neighborhood kids on an expedition to the Hawthorne Institute, a reclusive research facility two miles into the woods.

They discover a mausoleum on the grounds. Billy gets trapped in its iron gate while the group flees from a security guard.

Ethan runs. He leaves Billy behind.

That night, in the supposed safety of Ethan’s backyard tent, the two boys argue bitterly. Ethan tells the ghost-obsessed Billy to “just die and become one.”

Hours later, someone slashes the tent fabric. By morning, Billy is gone.

Thirty years pass. Ethan’s wife Claudia has died. His parents have moved away. He returns to the empty family home on Hemlock Circle, battling chronic insomnia and a recurring nightmare of that night.

Almost immediately, strange things begin.

Motion-activated garage lights trigger in sequence. Battered baseballs — identical to the ones Billy used as a childhood signal — appear in his yard.

Then Detective Ragesh Patel, a former neighborhood kid who was there in 1994, delivers devastating news: human remains confirmed as Billy’s have been discovered at the base of the waterfall near the Hawthorne Institute.

Ethan launches his own investigation. He uncovers his mother’s secret employment at the institute and her firing after witnessing a strange ritual. He learns about Ezra Hawthorne, the billionaire founder rumored to dabble in the occult and parapsychology.

Desperate to unlock his own blocked memories, Ethan enlists Detective Cassandra Palmer to help with a radical experiment. She slashes a new tent while he sleeps inside it.

The reenactment works. A repressed memory surfaces: Russ Chen, the neighborhood kid who was always the third wheel, was outside the tent that night.

Ethan confronts Russ. Russ admits to slashing the tent — a jealous childhood prank — but swears he didn’t take or kill Billy.

The truth comes when Andy Barringer, Billy’s younger brother, kidnaps Henry, the young son of former babysitter Ashley Wallace. Andy drags everyone to the falls, believing Ethan is responsible for Billy’s death.

On the ledge, Ashley Wallace confesses. She was fifteen that night, driving without a license, slightly buzzed. She hit Billy with her car on the dark road through the woods.

Panicked and terrified of ruining her future, she wrapped his body in a blanket and threw him over the falls.

During the confession, Henry — devastated by his mother’s revelation — stumbles backward off the cliff into the churning water below.

Ethan dives in. In the dark, murky depths, he feels a benevolent, invisible hand guide him toward the boy. Both Ethan and Henry later believe it was Billy’s ghost.

Ethan saves Henry. The police arrive.

Ashley is arrested.

Eighteen months later, Ashley serves a prison sentence for manslaughter. Ethan has legally adopted Henry. He remains on Hemlock Circle, the last original resident, finally at peace.
