A young girl charged with watching Santa's horses must track down an escaped steed in this sequel to the 2006 family drama Winky's Horse. Santa has departed from Spain, and he won't be back until St. Nicolas' Day the following year. In Santa's absence, Winky Wong has been asked to look after his horse Amerigo. Enchanted and eager to do her best, Winky soon commences taking riding lessons on Naf-Naf the pony. Her skills steadily growing, the young girl is taught how to tend to the horses by her wise Aunty Cor and Uncle Siem. But while Winky is determined to ride Amerigo, Aunty Cor and Uncle Siem reject the idea by stating that Amerigo is too much horse for her to handle. Upon learning that her mother is pregnant, the conflicted Winky looks forward to having a sibling but fears that she will no longer be the center of attention. One day, while tending to Amerigo alone, Wiky seizes the moment and attempts to ride Santa's horse. Unfortunately things don't go as planned, and Amerigo breaks free from his paddock. Though Winky sets off on her bike to track down the missing horse, Amerigo is nowhere to be found. What's a girl to do after she's lost Santa's favorite horse?
