A great tragedy happened in Appleoosa more than a decade ago, one that left half of the element bearers dead, and left the town abandoned. The incident has been left uninvestigated, until now.
Applebloom, third bearer of the element of honesty after her sister Applejack and brother Big MacIntosh, goes to Appleoosa to investigate the town, looking for information that will lead to the solution to the mystery of why her sister died there.
While she's on her own, she has tools with her to help her: a camera that takes animated pictures, and a crystal to record what she says. What will she discover about her big sister and her cousin? Will she want to remember what she learns?
