It’s been a year since Sarah, Hannah and West escaped the epic funhouse that changed their lives forever. Now known as the Deltas, the three best friends work at The Delta Game and spend their time tackling every challenging escape room they can find.

Then a mysterious invitation arrives from The Mystery Mansion, a brand-new rival funhouse claiming to be the biggest and best escape house ever. Its cryptic owner challenges the Deltas to test it on opening day, with a $10,000 prize if they successfully escape.

Determined to protect their beloved Delta Game, Sarah, Hannah and West accept the challenge. But their plan quickly unravels. Nothing inside the mansion is as it seems.
