Since getting a job at Top Tier stables, Annie has had her mind set on just one thing: earning enough money to buy a horse of her own. When she reaches her savings goal, she bids on a horse at an auction and buys Poco, a four-year-old Buckskin mare that Annie couldn't love more. But someone is trying to sabotage Top Tier, and a terrible fire breaks out at the stable. Annie must summon all her courage to save her beloved horse as well as many others in an act of heroism she didn't know she was capable of doing.
