Seven strangers, men and women, woke up in strange cells.
With no memory and no reason, they are trapped in a strange building isolated from the world.
The only rule comes from a frighteningly accurate brass alarm clock:
"Rule 1: Every evening at dusk, when the bell rings, gather here."
"Rule 2: Every day, one person needs to enter the 'Between Echoes' and face the past."
"Rule 3: Find out the truth about 'Silence' within seven days. If you fail, you will fall here forever."
"Rule 4: Violence is prohibited, violators... Will be erased."
"Between echoes" is the corridor of purgatory. Everyone who walks in will be forced to relive the most unbearable, frightening, and most forgotten memory moments in their lives. The pain is magnified, the details are scrutinized, and the cold questioning penetrates into the depths of the soul - what did you see back then?
Survivors of a car accident on a rainy night, doctors who hide evidence, guilt-ridden businessmen, ferocious laborers, cowardly women, unfathomable old men... When their respective "repercussions" are staged one after another, the fragile alliance is full of suspicion. The only clue points to the bell that rings on time every day, but has contradictory meanings - does it guide the way out, or does it cover up the truth?
The countdown has begun. In the labyrinth of memory and the web of lies, they must piece the pieces together and face the deepest ghosts in their hearts.
On the seventh day, when the final bell rings, will everything finally... Fall into silence?
