Dorothy is staying as a guest at a country house. Robert is mistaken as her partner and put in the guest suite. Fearing he'll have to stay in the servants' quarters if the truth is discovered, they decide to keep up the pretence. Things get difficult when mutual friends arrive.
The McNab residence has been burgled. Robert worries that he will be a suspect because of a valuable painting stolen from his previous place of employment.
Dorothy and Robert argue about who can control the heating thermostat. Dorothy and Robert agree that if she can enter his exclusively all male club for three hours within three days, she can take control of the heating.
