Saint Jude review – delightfully disturbing immersive theatre in creepy clinic

Petty France, London
Taking part in a trial shift to help coma patients wake up, the tension grows as it slowly becomes clear why you're really mining strangers' secrets

A deliciously uneasy atmosphere lies under the mask of a welcoming smile in the intensely unsettling Saint Jude. We're here to volunteer for a good cause, but as we're shuffled through eerie, clinical corridors, it quickly becomes clear that nothing is as it seems.

Taking part in this immersive, tech-centred show is like walking into a choose-your-own-adventure video game: inventive and enjoyable, if a little restrictive. We're on a trial shift to be a Guide Star" for Saint Jude, a private company that purports to connect volunteers like us to Sleepers", people in the depths of a coma. Our job, we're told by beaming clinician Stefan (Bryan Moriarty), is to talk to our Sleeper and dig up details that will help them wake up.

Saint Jude from Swamp Motel runs until 12 March.
