When Lucas gets home, he immediately begins trying to contact Andy with no success. Andy doesn't have anyone else to care about him. Lucas' wife hates him, his ex-wife hates him, his employers are on the verge of firing him because of his sex addiction. Only Lucas cares.Meanwhile, Sergeant Wendy Elliott of the Seattle Police Department is looking for a friend who has disappeared. The friend was a hooker that Wendy met while she was working Vice. Her only clue is a partial license plate of a black Suburban that was near where Lupita disappeared. The Suburban is owned by Ditto's Funeral Homes Inc. owned by Bobby Ditto.
