Having censured Richard for polluting the environment in his new helicopter, Audrey is unable to pay for her car to be repaired. After agreeing to run a friend's riding school, she sees the answer to her transport problem: getting about on horseback. But she has a run-in with an officious traffic warden for illegally parking the horse. Horsepower does, however, offer an opportunity to give the pensioners' outing a pleasant surprise.
