The Prodigal

When Angel (David Boreanaz) learns that Trevor Lockley (John Mahon), the father of Det. Kate Lockley (Elisabeth Rohm), is involved in a demon drug ring, it brings back painful memories of his troubled relationship with his own father and his transformation into a vampire. Someone, it seems, is peddling PCP-like drugs that turn normally peaceful demon races such as the Kwaini into killers. Kate reluctantly teams with Angel to investigate, but she's unprepared for the revelation that her dad, a retired cop, is in leagues with the dope-pushers. Soon, though, Mr. Lockley turns up dead, emotionally shattering Kate and further eroding her tenuous alliance with Angel. Nonetheless, Angel rescues her from the turncoat demons who killed her father. Throughout the investigation, Angel is haunted by his memories of quarreling with his father, becoming a vampire, and then killing his entire family.
