After getting a car ride from an unknown man, Lisa (Gaia Weiss) wakes up in a tube, dressed in a high tech catsuit with a strange bracelet on her wrist. A door slides open and the challenge begins: Lisa must scramble through the tunnels as fast as possible, squeezing through impossibly narrow gaps and learning the rules of this deadly game as she goes along. She quickly realises that the counter clock on her wrist warns of imminent danger. And the discovery of the roasted and decaying remains of a former contestant reveals that the consequences of failure are messily final.
