The world's oceans hide three million shipwrecks. Each one is a time capsule - a moment frozen at the point of sinking; a moment lives changed forever. Mallinson Sadler Productions, the makers of National Geographic's acclaimed ‘Drain the Oceans’, delivers a deep-sea mystery series that takes viewers on a thrilling journey to the bottom of the sea. Join real-life shipwreck hunters as they uncover the gripping stories behind the most fascinating wrecks in our oceans. Quality actors will deliver the first-hand accounts of survivors and witnesses while stunning VFX will be used to return the wrecks to their former glory.

Using cutting-edge underwater technology, ‘World's Greatest Shipwrecks’ delivers an unparalleled view of the underwater world, telling powerful stories of death, desperation, and survival from history's most dramatic maritime disasters to unpack their mysteries.
