In 1910 Miss Beatrix Potter is able to get away from her parents and goes to her properties in the Land Between the lakes, Hill Top Farm and Castle Farm, where trouble is brewing in the hamlet. When Mr. Harmsworth barricades the foot path running through his property, Applebeck Farm, claiming he did it because someone lit a fire to his hayloft, and another fire ruins a place of business, Miss Potter is on the case!
