Pretty much. Horse wasn't ready for a four-star, rider takes him there anyway, runs his ass downhill at a jump-through fence (which he is known to be balky at), he gets a bad spot b/c of it, hooks his forelegs and flips, breaks his neck etc.

...and I whispered to the horse; trust no man in whose eye you don't see yourself reflected as an equal.
