"Big" Jim Cooley: the stallion that everypony in Buck City looks up to, both in fear and awing respect. His skill out on the plains is matched only by his madly inflated ego.

Applejack, set out west to seek fortune as a cattle wrangler, gets pulled into an adventure that she can't possibly turn down. But when she finds out this "typical" cattle run is a suicide mission that goes right across Buck City's desolate and savage-ridden plains, will she ditch a chance at the opportunity of a lifetime?

Based roughly on the song Ballad of Big by Genesis
