It was supposed to be an unforgettable Halloween experience for all invited guests: A private murder mystery party in the style of the 1930s takes place on a historic train. There is an exuberant atmosphere and the murder mystery dinner brings back memories of the classic 'Murder on the Orient Express'. But a group of real thieves has mingled with the passengers and as soon as the train picks up speed, disaster strikes: the crooks' attack goes wrong and the engine driver is seriously injured. Much too quickly, the old train derails in a sharp curve and plunges down a steep slope, right into the middle of a dark mountain lake. Slowly, the train sinks with its passengers towards the bottom and ice-cold lake water penetrates inexorably into the interior. But what awaits the survivors at the bottom of the lake will take their last breath away! Down there, in the darkness of the bottom, a cruel, ancient monster has been lurking for fresh prey for a very long time...   DVD 2026 New
