The award-nominated COLAB Theatre returns for a third year running with a brand new Immersive Horror Experience. You are invited to face your fears once more. Step into the unknown. 

“The history of chocolate is bathed in blood.”

Those who do not remember the past are condemned to repeat it. Those who turn their backs ensure the wrongs committed cut a deep swathe in history, and those brave enough to dig deep can change the course of the future forever.

The truth must come out. 

A chocolate factory shrouded in secrets, a family compelled by greed, and a vengeful spirit lurking below. Put your mind to the test as you race to unravel four mysteries spanning generations. Challenge your bravery as you plunge into the depths of an abandoned basement, scrabbling in search of the vital clues in order to save a life. But steady your nerve, for should you make a sound, Hell’s wrath shall befall you.

Forty years to unwind. Four victims to free. One raging spirit...

Your life is in your hands.
