After three weeks of cliffhangers, the epic drama reaches its conclusion, 100 years to the day of the real-life tragedy. The ship hits the iceberg and panic takes hold. As the women and children board the lifeboats, Georgiana and Harry savour the few precious moments they have together, Barnes gives Watson a parting gift that will change her life for ever, and Louisa makes a surprising promise to Hugh. Below decks, Paolo tries desperately to save his brother and Jim searches for his daughter. As the liner is dragged underwater, the next few hours will decide who will live. In yet more Titanic viewing, we have Titanic: The Missing Link (10.00pm. UTV); Words of the Titanic (11.15pm, UTV); and Titanic Centenary (10.25pm, BBC1).
