Cheerful Weather for the Wedding

The last summer, shown in major flashbacks, dashing archaeologist Joseph has brilliantly flirted with upper middle-class girl Annie Thatcham, delighting her cute naughty kid brother Jimmy and even her headless sister Dolly, yet antagonized their mother, stuck-up widow Thatcham. When Annie bluntly refused to accompany him on a Greek excavation, she was sent on Albanian holiday, met stuffy diplomat Owen and got engaged. At the wedding day, the sisters realize she's giving up on her best chance for happiness, and Joseph turns up, but the party guests and obligations keep getting in the way of actually talking it trough. - IMDb
