2x5 - Touching Evil

Creegan and Taylor investigate when a young boy is snatched from the back garden of his parents' house. The search leads to Annie Jordan, who claims to be the boy's biological mother – and that she sold the boy to a dealer who internationally trades in children. As the team discover links to a paedophile ring, Creegan has to deal with personal tragedies of his own when a relative of a murder victim tries to kill his ex-wife and children by setting fire to their house.
