Adam couldn't have been more excited to start his first day at the Singapore Crime Museum in 2043—when prisons no longer exist and Changi Prison has been repurposed into a bustling commercial hub. Crimes of the past are now eerie exhibits, drawing visitors into a dark history that feels more alive than ever.

On his morning tour, with 12 visitors registered, Adam begins recounting the infamous murder committed by Adrian Lim. But as he delves into the chilling details, he notices something amiss—one of the visitors, Bantam, has mysteriously vanished.

A frantic search leads to a horrifying discovery: Bantam has yet to leave the museum. Instead, he's been transformed into a miniature figurine trapped inside a glass display case.

As the day unfolds, the line between reality and nightmare blurs. One by one, the visitors' life stories—and Adam's own—are revealed in shocking, heart-pounding scenes. Each person seems to be facing a reckoning with their past, with the museum as their judge.

Can Adam navigate the twisted labyrinth of the crime museum, where the sins of history come to life? Or will they all remain prisoners of their dark secrets, caught in a web of historical crimes that refuse to stay buried?
