On the night Joel Stevens attempts suicide, he experiences a vision that instills in him an obsession to ascend as an angel.

Rescued by Donovan, a passing vagrant who claims to be an angel capable of leading him through ascension, Joel yields to his guidance.

Joel welcomes Donovan into his home, where tensions build with his wife, Sarah, who believes her husband is having a psychotic breakdown.

Donovan insists Joel must put his life in his hands and helps him achieve three near-death experiences where he visits broken, incomplete souls in Purgatory. Each visit diminishes Joel's physical and mental capacity, bringing him closer to a state of being "less," which is essential for ascension.

After Joel's final visit to Purgatory, Sarah physically intervenes trying to wrestle Joel out of Donovan's grip.

Joel and Donovan get out and race to Philadelphia to fulfill Joel's destiny. They arrive at the Pyramid Club, a site used across the millennia for those ascending. But little does Joel know that his destiny has been written for centuries, and not everything--or everyone--in his life is what it seems to be.
