Every horse has a talent or two. Some can sit, some can jump over obstacles, and some can select a button for a treat. For one particular draft horse, Dok Saau, his talent is in writing. He does not just scribble letters in the ground as a trick, but he also uses his talent to express his own thoughts to his bemused owners.
Surprised by his strange talent, his owner Chang Gao brings him to the Horse Fair, where he beats the other horses by writing proper answers to several questions. After a DNA scan, he is revealed to be a unicorn: even though he was supposed to be released into the wild, the authorities let Chang Gao keep him so that he might become a local attraction.
Yet even as he tries to adjust to his new life as an animal celebrity, every now and then he faces recurring nightmares from his troubled past. As he seeks Chang Gao’s help, will he be there to help him defeat his fears? Or would they instead attract something much worse: something that could threaten his comforts or even his own life?
