In the town of Thornvale, wrapped in perpetual mist and secrets, Elian Cross, a quiet 19-year-old outsider, inherits his estranged grandfather's old mansion. But the will contains a strange clause:
"You must live in this house for 13 days. You must not leave at night. You must never speak your name aloud after dusk."
As he settles in, Elian begins to experience strange phenomena: whispers through the walls, locked rooms rearranging themselves, and ghostly reflections of himself in mirrors doing things he didn’t.
Every night at 2:09 a.m., the grandfather clock chimes thirteen times, and a hidden door opens.
Inside it lies the Echo Room — a space where memories don’t reflect the past, but predict a possible future.
Each night, Elian meets versions of himself — braver, darker, broken — all offering him choices.
He starts receiving letters addressed to “The Future Corpse of Elian Cross.”
Worse: someone is watching him. And they remember things he hasn’t done… yet.
The townsfolk avoid his mansion. They speak in cryptic ways:
"He’s not the first Elian we’ve met. But maybe he’ll be the last."
As the 13th night approaches, Elian learns the truth:
His grandfather built the house as a dimensional mirror, to trap a version of himself who destroyed his own world.
Elian is one of many — but the only one who never left the Echo Room.
He might already be dead… and this life is a repeat.
On the final night, he’s given a choice:
Escape the loop by sacrificing his memories.
Or stay and face the version of him that murdered his grandfather.
He chooses to fight.
In the Echo Room, Elian faces his own worst version — arrogant, powerful, merciless. But with each memory he sacrifices willingly, he weakens the monster inside.
In the end, Elian burns the mansion down and walks out into the fog.
He no longer remembers his name. But he remembers who he chose to be.
The townsfolk nod as he passes.
"This time, he was different."
