While trying to make his sister’s wedding day go smoothly, Jack (Sam Claflin) finds himself juggling an angry ex-girlfriend (Freida Pinto), an uninvited guest with a secret, a misplaced sleep sedative, and the girl that got away (Olivia Munn) in alternate versions of the same day.

This is a wedding comedy about chance and how things have thousands of ways to go wrong.  It iss mostly funny but it does have some heavier moments. It is revealed that Jack and Hayley’s parents couldn’t be at the wedding. I assume due to their somber tones that they have both passed. Dina has also lost her mother to terminal cancer in the years since Jack and her have last met. These deaths are played as story beats but they do come out of nowhere so be prepared to hear about deaths.
