Inspector Morse - Episode 20: Promised Land [DVD]

A criminal named Peter Matthews dies of AIDS in prison, prompting an inquiry into his case. Morse believes that Kenny Stone, an informant who helped convict Matthews, held back information from his story. Stone has been relocated to Australia, and Morse and Lewis travel there to follow up, hoping to firm up the evidence and prevent the release of other members from Matthews' Oxford gang.

When they reach New South Wales, Stone, now named Mike Harding, is missing. His mother-in-law's room at her care home has been ransacked, and she is hospitalised. Harding's wife Anne does not welcome their presence, and Morse and Lewis believe she is lying about not knowing where he is. Morse tells police officer Scott Humphries, who responds to the attack, that he is a private detective whose client is considering leaving money to Harding, but makes little progress.

Lewis soon realises the Oxford mobsters looking for Harding located his whereabouts through the mother-in-law's subscription to an Oxford newspaper. When the Hardings' daughter, Karen, is kidnapped, Anne's mother dies from the shock of the earlier attack, and Anne goes to the police, Morse and Lewis explain who they are, but they are told they are not authorised to conduct an investigation locally.

Harding's oldest son Dave, who had previously told Morse he didn't know where his father is, now tells him his father recently called him and he thinks that Harding might be in a caravan he owns. When the two of them arrive at the caravan, they find Harding is dead, an apparent suicide. Morse and Lewis speculate that Harding killed himself either because he expected to be found out or because Anne was having an affair with Humphries. Anne admits that Harding's original evidence against Peter Matthews was false and that, in that instance, Matthews was innocent.

Karen's kidnapper makes contact again, demanding to see Harding. Morse tells him he will bring Harding and sets up a meeting. Morse and Lewis realise that the kidnapper is Paul Matthews, Peter's younger brother. Feeling responsible for having helped convict Peter and for the two subsequent deaths, Morse goes to the meeting unarmed and attempts to save Karen by offering his life in exchange.

When Morse's attempts to reason with Paul are unsuccessful, Anne runs out of hiding to rescue her daughter. Humphries tries to stop her but is shot by Paul, who then is then killed by a police marksman. Anne agrees to return to England to set the record straight.
