A fallen angel attempts to redeem himself after failing to protect a child in his care. The Angel is racked with guilt over the death of the child, which he blames on himself. In an attempt to make amends he involves himself in a crime case that follows on from the child's death. However, angels face many problems operating on Earth. Modern rational people aren't easily convinced of their existence and detectives involved in the case soon perceive the Angel as a suspect rather than an ally.
