14 September 1943: The legendary submarine Y1 “Katsonis” was sunk north of the island of Skiathos by the German submarine chaser UJ 2101. Through the book of XO Elias Tsoukalas who escaped capture and had to swim for nine hours to reach shore, secret documents, and crew members’ diaries, the documentary unfolds the human stories woven around the submarine. Seventy-five years later, with the support of the Hellenic Navy, we search for the submarine sunk at 253 metres depth and film the wreck for the very first time.

Bajo las frías y salobres aguas del mar Báltico yace uno de los grandes misterios sin resolver de la Segunda Guerra Mundial. El 10 de marzo de 1945, el cuerpo congelado del capitán de un submarino alemán... aparece en las frías costas de la isla de Föglö, en Finlandia. Se trataba del comandante del submarino U-745, el capitán de la Kriegsmarine Wilhem Von Trotta. Pero el submarino, y el resto de la tripulación, parecían haberse desvanecido en las profundidades marinas. Tras decenios sin notícias sobre el emplazamiento del navío hundido, un grupo de buceadores finlandeses decide sumergirse en aguas del Golfo de Finlandia, decididos a hallar al fin el submarino del capitán Von Trotta.

In 1968 the Soviet ballistic missile submarine K-129 sank in the Central North Pacific. American intelligence located it within weeks of its demise. The CIA crafted a secret program to raise the submarine in 1974. Now after much secrecy, this story can be told, by the men who made it happen and with never-before-seen footage of the actual salvage attempt, and new evidence of the project's successes and failures.

The ITN-produced documentary promises to “go beyond” news coverage and bring viewers up to date, while examining the wider context about the voyage, its passengers and the fascination with the Titanic shipwreck. The film will also talk to experts and look at the rise of extreme tourism.
