Ragnarok

An archaeologist widower sets off on an expedition to northern Norway with his two children in search of a legendary bottomless lake and clues to unravel the secrets of Ragnarok, the end of the world in Norse mythology. As they explore the remote area, their excitement is cut short when they discover an ancient site that unleashes a terrifying creature - a pebble-skinned sea serpent reminiscent of Viking ships. The group narrowly escapes multiple attacks by the serpents and must navigate treacherous terrain to uncover the truth behind the mysterious stone tablet and the Norse legends.
