Matt Berry plays a corrupt and bizarre hypnotherapist taking unsuspecting clients on twisted, misleading journeys through their subconscious. Each episode sees the doctor dealing with a different client who has come to him for a different problem (quitting smoking, fear of water, etc). As the patient is put under hypnosis, we 'enter' their mind, and all the various situations the hypnotherapist takes them through are played out for us to hear. The result is a dream- (or nightmare-) like trip through the patient's mind, as funny as it is disturbing. Also starring Katherine Parkinson, Morgana Robinson, Simon Greenall, Jack Klaff, Tara Flynn, Alex Lowe and Derek Griffiths.
