For the aging John Hamilton, life after losing his son is a constant cycle of drinking and passing out on the curbside of the Moonlight Pub. This contract killer has long abandoned any hopes of redemption. But this cycle soon attracts Death, or rather, a seraphim called Azrael, who promises to find the killers of his son if Mr. Hamilton fulfils a contract. With nothing to lose and lifetimes to take, Mr. Hamilton willingly signs, desperate to satisfy his only friend.
