When a lonely young boy named Angus discovers a large, mysterious egg along the shores of Loch Ness, no one is prepared for what lies within. He soon discovers that the strange, mischievous hatchling inside is none other than "The Water Horse", the loch’s most mysterious and fabled creature!

But with the Water Horse growing ten times its size every day, Angus finds it increasingly difficult to keep his new friend a secret.

Two-time Academy Award(R) nominee Emily Watson (1998, "Hilary And Jackie"; 1996 "Breaking The Waves"), Alex Etel, Ben Chaplin ("The Thin Red Line"), David Morrissey ("The Reaping") and Brian Cox ("Running With Scissors") star in this heartwarming tale from director Jay Russell ("Tuck Everlasting") and written by Robert Nelson Jacobs ("Flushed Away").
