The audience arrive aboard Lightship 93 as an expedition from the Institute of Forking Paths, sent to find the previous expedition that went missing.
Once aboard they meet the ships inhabitants and discover that the ship houses a dreadful machine: The Sepulchre. The Sepulchre bends time, prolonging the lives of all those aboard, but also preventing anyone from leaving.
The audience are charged with the mission of dismantling The Sepulchre. The only means to do this is to find the Sepulchre’s creator; the enigmatic Captain Nemo. Nemo has lapsed into a catatonic state and they must complete a series of challenges to awake him and leave the ship alive. However, our stories villain, Victor Barbicane has other plans.
He tricks the audience and Nemo into helping his own dastardly ends of taking the Sepulchre for himself.
Only by rallying the ships crew and rousing the spirits of A fallen hero, may the audience defeat Barbicane and find a way to escape the ship.
But there are tricks at every turn, and they must constantly ask themselves – who can they trust on this mission? There are powerful forces at work on both sides, and they might just hold the key to survival.
