Ryan, Josh, and Chelle don’t think much of it when they steal a few coins from a wishing well for bus fare back home. But to steal the coins from a well spirit is to take on her obligation of granting wishes, and soon the kids find themselves developing the powers to do just that – from the eyes on Ryan’s knuckles that see things they shouldn’t, to Chelle’s newfound ability to speak the thoughts of strangers, to Josh’s sudden affinity with electromagnetism. It’s then that they find that the wishes people make in their hearts are infinitely darker and more dangerous than the ones they speak aloud, and that the changes the well witch has wrought in them go deeper than they think.
