First Cut returns for a fifth run. Rachel Williams's 'First Cut' documentary tells the story of Thanos Papalexis, the British playboy-businessman who last year was jailed for murdering an intransigent sitting tenant who stood between Papalexis and a lucrative property deal. After the murder, the debt-ridden killer reinvented himself in the US, shacking up with a porn star and hosting fundraisers for the Clintons. (NEW SERIES: 5)
