When Evil Calls centres around the mysterious appearance of a text message that grants the students of at Wilburn High School their wildest desires.

Willburn Hall is your average six form college, with a complex hierarchy. Towards the bottom is Samantha (played by Jennifier Lim) one day when she is walking home after an average day, a door falls out of the sky. Then out of the door comes a Clown (played my Oscar Pearce). Samantha is then granted one wish via text message in return for passing the message on two people. The clown or evil genie goes on to cause havoc in the college with all the pupils owning mobile phones....Will the pupils of Willburn Hall be able get through it?—Anonymous
