Hij vraagt om wat te eten en een tijdelijke schuilplaats. Rose is in de tijd dat Tommy vastzat getrouwd met de nette, maar saaie George Sandigate (Edward Chapman) die twee mooie, maar opstandige dochters en een puberzoon heeft. Als iedereen op deze regenachtige zondag het huis uit gaat, haalt ze Tommy binnen...
