Time Turner, Ponyville's resident time keeper, comes to Phillip Finder with a case; he's sure that he's being followed, but doesn't know why or by whom.

But with Phillip on the case and Rainbow Dash helping, it should be easy to find out who these spies are and what they want with a clockmaker, right?

Wrong.

Soon after contacting Phillip, Time Turner disappears and the case becomes a race to identify the captors and find their hideout before Time Turner's time runs out.
