When the coastal town of Marrow's Bay begins rebuilding after a catastrophic flood, retired engineer Silas Karr volunteers to inspect the damage — and stumbles upon something no one was meant to find. Beneath the ruined wing of the old school lies a sealed chamber, untouched by time, filled with children's clothes and photographs of faces no one seems to remember.

As Silas begins to unravel the mystery buried under years of water, silence, and complicity, he uncovers unsettling patterns in town records, missing person cases, and his own architectural past. The deeper he digs, the more he realizes that the tragedy everyone mourned may have been something else entirely.

Why were these children hidden? Who recorded their existence only to erase it? And how much of Marrow's peaceful history is built on something no one wants to name?

Layer by layer, Silas is drawn into a quiet horror — one that reshapes his identity, his legacy, and the meaning of safety itself.

How do you repent for something you didn't remember doing?
