Aunt Priscilla, the Bishop and his wife, disapprove of Ronald because he was expelled from Oxford and dances at night clubs. They see the Rev. Augustine Mulliner, who is cheerful and energetic because he takes a tonic called Mulliner's Buck-U-Uppo, and Ronald suggests that they give some of the tonic to the Bishop so he will be more accepting of him. Ronald thinks he has no chance of marrying Hypatia, and they make plans to have a goodbye dance at a night club which is having a Gala Night, fancy dress optional. Augustine is more optimistic and tells Hypatia he will help her marry Ronald. Augustine tries to convince Hypatia's aunt and uncle to accept Ronald, but is unsuccessful. Later, the Bishop is strangely cheerful and borrows a Sindbad the Sailor costume from Augustine. Augustine remembers seeing the Bishop acting similarly once before when he took some Buck-U-Uppo (during the events of "The Bishop's Move"). Ronald and Hypatia do not go to the Gala Night since Ronald hears there will be a police raid. Hypatia tells Augustine she gave the Bishop and his wife some Buck-U-Uppo. Augustine realizes she gave them too much. Hypatia says her aunt borrowed a Columbine costume from her. Hypatia and Augustine realize the two went to the Gala Night. The Bishop and his wife dance at the party and come back, chased by a policeman named Cyril Smith. After Augustine gives Cyril a drink with Buck-U-Uppo, Cyril becomes friendly. The Bishop and his wife cheerfully consent to Hypatia marrying Ronald. Hypatia, her aunt and uncle, and Cyril all go to wake up Ronald and tell him the good news. Augustine has to stay behind to write a sermon but is very happy for them.
