Eerie horror anthology with Donald Pleasence. A psychiatrist recounts four disturbing cases to a colleague, from a boy with an imaginary tiger to a cannibal luau organised by a literary agent. (1973)

Enigmatic asylum owner Dr Tremayne houses four very special cases. Visited by his colleague Nicholas, Tremayne explains his amazing and controversial theories as to why each patient went mad, be they a ritualistic 'luau', a time-travelling bicycle, a toy tiger, and a tree stump.
