A boy finds an interesting egg. His curiosity leads him to protect it and want to figure out what will come out of it. He didn’t realize that it would turn into something magical. The boy and the Water horse grow a strong relationship together in this wonderful story.Narrator Brian Cox (his character is not identified) tells of WWII era in Scotland at the famous loch, where young Angus MacMorrow finds an egg at the shore and nurtures the lovable monster until he has to go to the loch to survive. The Scottish regiment occupying the home and the new handyman, Lewis Mowbray (Ben Chaplin), complicate life and endanger the elusive monster. Although the usual clueless mom (Emily Watson) and dangerous thugs are here to further the horror genre staples, the challenges Angus faces are instructive about the collision of reality and fantasy for an adolescent.
