When a world-famous trick riding horse is stolen one week before the biggest event of the year, the team is desperate for answers. The police dismiss the case as a publicity stunt, leading the distraught owner to hire the Robinson Family Detective Agency. With the trail cold, amateur sleuth Becky Robinson saddles up and goes undercover as the newest rider. Hold your horses! Becky can't even ride a pony, much less dangle upside-down at a full gallop. The investigation pits Becky in a race against the clock.  Can she beat the crooks in their twisted game of hide and seek in time? Or will the horseplay lead to murder? ----------------
