It's Christmas in the McNab household and both Dorothy and Robert say they're going away for Christmas. Both return to the house to find each other has a friend with them. To make matters worse Dorothy's cousin Clarence turns up uninvited.
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.
When Dorothy is out shopping she meets a group of people on their way to India. She invites them back to the house for some food, but there's one problem, none of them are allowed to speak.
