CUCUMBER Channel 4, 9pm Sixteen years after the hit Manchester-set series Queer as Folk appeared on the small screen, Russell T Davies returns with this drama exploring the passions and pitfalls of 21st-century gay life - one of three interlinked shows for Channel 4, E4 and online. When a 46-year-old man and his long-suffering boyfriend embark on a disastrous date night, nothing will ever be the same again. At work, Henry is drawn to the enigmatic Freddie, while Lance greets newcomer Daniel, but both friendships are set on a course to explode.
SURVIVING THE HOLOCAUST - FREDDIE KNOLLER'S WAR BBC2, 9.30pm The eponymous star of this moving documentary recalls his life as a young Jewish man during World War Two. Freddie's story is a dramatic, and at times, amusing account covering his family life in Vienna during the 1930s; the German occupation of Austria and his flight to Belgium. He also reflects on his time in Nazi-occupied Paris, where he lived and worked in the red-light Pigalle district for more than two years, socialising with dancing girls and entertaining German officers. However, an interrogation by the Gestapo eventually led to him moving on again. Following a brief spell in the Resistance, the Nazis eventually caught up with Knoller and his life in Auschwitz began. Now in his nineties, the Holocaust survivor speaks directly to camera while his memories are supported by archive footage.
DEATH IN PARADISE BBC1, 9pm The Saint Marie Heritage Society is re-enacting the French invasion of the island when its president dies. At first it looks like an extreme reaction to a dodgy stew as the rest of the group have fallen ill - but when lab reports reveal there was poison in the pot, Humphrey is left wondering why the victim was the only one to end up in the mortuary. Meanwhile, Dwayne takes Humphrey out on the town to show him his own way of celebrating the founding of Saint Marie.
