BRAN'S MYSTERY ISLAND HOUSE RULES SYNOPSIS:
The movie kicks off with some running as the gang prepares for their next big mystery party. The Baroness drops a bombshell — they’re considering opening a second location: Mystery Mountain. To test it out, Jason and Emilia are sent for a trial weekend as guests. Everything seems perfect, and they’re both very impressed.
At dinner, things get awkward when the staff starts arguing. Reagan, the on-site cop, begins questioning the company’s hiring practices. But soon, it’s game time — and the tech is mind-blowing, featuring Bluetooth phone integration and even a hologram. Jason and Emilia dive into solving the puzzles, but then chaos strikes. A tiny dart shoots out of a bookshelf and hits Reagan in the neck. It’s tipped with honey — which she’s allergic to. Moments later, their Bluetooth game box explodes. When they return to the room where Reagan collapsed, her body has vanished.
One by one, more people “die” — three victims in total — yet none of their bodies are found. Emilia realizes she was the actual target, since she too is allergic to honey. Determined to solve the case, Jason and Emilia hunker down with their trusty whiteboard to crack the mystery.
In the end, the shocking twist is revealed: it was all part of the game. No one really died, and Mystery Mountain remains murder-free. Relieved, Jason and Emilia celebrate the victory with their long-awaited first kiss.
