When Evil Calls centres around the mysterious appearance of a text message that grants the students at Willburn Hall their wildest desires. A-cup Alice wants bigger breasts, until her cup runneth over in an explosive mathematics class. Hilary would give her right arm to lose weight – and the blades of a kitchen waste disposal unit oblige. One by one, Willburn’s students learn a lethal lesson: be careful what you wish for.
