Cheerful weather for the wedding

Today is Dolly's (Felicity Jones) wedding, and her family is arriving at the manor house with all the cheerfulness, chaos and petty grievances that bubble to the surface at such gatherings. However, when the time comes for the beautiful but secretive bride to make her grand entrance, the uninvited appearance of Dolly's lover from a previous summer, Joseph (Luke Treadaway), cuts short her desire to join in the festivities and embark on her new life with her new husband in South America.
