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.
