Royal Season pops over to the royal stables in this documentary. Famed for their plumed helmets and shining breastplates, the Household Cavalry is the oldest regiment of the British Army, and their day-to-day lives at Hyde Park Barracks, London are not the least bit dull. We’ll see the preparations for the queen’s birthday parade, and get to meet the latest recruits, who’ll receive all the rigorous training required to serve in this elite regiment.
