Captain Ladybird & Herbert
- two Shire horses & a Suffolk Punch
- are not pleased when Jenny a retired seaside donkey arrives at the Old Horses Home. Its supposed to be a home for horses & they dont want to share their field with a common little donkey. Then rustlers are spotted in the area: thieves who like nothing better than to steal horses & ship them abroad
- to be made into horse pie! Can Jenny & her friends save the huge heavy horses?
