After narrowly surviving a harrowing possession, Damon Richter was left with abnormal abilities that allow him to help those fellow souls similarly tormented. Damon has embraced these powers for good until a routine exorcism goes terribly wrong forcing his family to suffer greatly. Thinking he left the world of possessions, exorcisms, and evil behind him, he must now use these skills to save his estranged daughter.

Disenchanted by the church and his devout Christian mother, 19 year-old Donald escapes Texas for the liberal Northwest and attends Reed College at the urging of his secular father. At Reed College, Don finds that his classmates, from all walks of life, are more anti-religious and anti-everything than he was prepared for. In an attempt to fit in, and more importantly, in an attempt to find himself, Don joins an activist group which forces him to question what he really believes in.
