A drama of the Westminster Inquiry into the sinking of the Titanic and its investigation into the role of the SS Californian. In the early hours of April 15, 1912, after colliding with an iceberg, RMS Titanic broke in two and sank into the depths of the Atlantic. The ship took with her 1,500 lives. Nearby steamship the Carpathia made its way through the treacherous fields of ice and arrived at the scene of the tragedy soon after the Titanic sank rescuing more than 700 survivors from the ocean's icy waters. The SS Californian, en route from Boston to London that same night, saved none. SOS - The Titanic Inquiry tells a lesser known side to the Titanic story. Made for BBC Northern Ireland, SOS – The Titanic Inquiry is based on the transcripts from the official British Inquiry into the sinking of the Titanic. Set in Westminster in 1912, this tense courtroom drama centres on the Inquiry’s investigation into whether or not the SS Californian was in close enough proximity to the doomed Titanic to help save some of the 1,500 passengers and crew who lost their lives. The Inquiry is headed by Lord Mersey (Tom Chadbon) with Sir Rufus Isaacs (Paul McGann) representing the Board of Trade. The drama shows Isaacs attempt to uncover the truth behind the SS Californian's activities on the night the Titanic sank as he brings the Captain of the Californian, Captain Stanley Lord (Stuart Graham) to the stand for questioning, along with Lord's crew of Herbert Stone (Owen McDonnell), Charles Groves (Iain Robertson) and James Gibson (Sam Holland). Frayed tempers, growing nerves and heated arguments ensue as each crew member of the Californian takes to the stand. Did the Californian witness distress signals from the Titanic? What happened to the missing scrap log book which detailed the ship's co-ordinates on April 14, 1912? And above all else, did the Californian fail in its duty to assist the Titanic? The drama was filmed in Belfast with the screenplay written by director Michael McDowell, adapted from the stage play "Blackness after Midnight" by Denis MacNeice.
