Not sure I can bear to watch but apparently it exposes the fact that thousands (yes it says thousands) of racehorses, including many young horses and previously successful horses, are sent to slaughterhouses each year. When will action be taken to stop this cruel and awful wastage in this industry? Never - because the betting industry is too powerful? At least something is being said in the programme about the dark side of what actually goes on. It's too often swept under the carpet and the general public's perception is that racing is a fun day out with lovely hats.
