The Loch Ness Monster is a legendary story that happened during the Second World War. It revolves around a lonely Scottish boy named Angus McMorrow ... Angus lives with his mother Anne and his sister Christie. He silently prays every day, hoping that his father who went to war will come home as soon as possible. However, when Angus found a mysterious and magical stone-like object on the beach, everything around him changed strangely, because he soon realized that he had brought home a magic egg with magical power. It looks like a cocoon wrapped in a shell, and soon hatches a strange reptile. It is violent and uncontrollable. It looks between horses, turtles and seals, and Angus called it "Kroos". Although Cross was in a hurry, he listened to Angus very much. Angus hid Cross in his bathtub so that his mother and sister wouldn't find out that he had brought back a monster. More dangers followed, and the arrogant officer Hamilton took a fancy to McMorrow's big house and used it as a safe place for the army to spy on Nazi submarines. Angus must be more careful. He needs to better hide his good friend with smooth skin and not let strangers stationed at home see him ... Fortunately, with the help of Lewis mowbray, Angus has successfully passed several times when he almost came out. The man who was found by his mother to help with odd jobs at home also has a mysterious past. Lewis told Angus that Cross was probably the legendary Loch Ness monster, a unique marine creature that only existed in Celtic mythology. Moreover, the growth rate of Kroos is amazing. Its size has almost become the size of a dinosaur. Angus can't hide at home any longer. He must drive Cross from his hiding place to the lake, hoping that he can swim to the ocean and run to freedom. However, in Haikou, there are militant troops guarding it, and they are alert to all suspicious ripples on the water-so how can a creature as big as Cross escape from these people's noses? In order to protect friends, but also to continue the legend, waiting for Angus will be an adventure full of fantasy.
