Love. Wedding. Repeat

Hayley (Eleanor Tomlinson) and Roberto (Tiziano Caputo) are getting married in LOVE. WEDDING. REPEAT. It's a beautiful day at a majestic hotel in Rome. Jack (Sam Clafin), Hayley's devoted big brother, will walk his sister down the aisle. They're best friends, confidantes, and because they're orphans, Jack has been the guiding light in Hayley's life. But Jack has something else on his mind, as well. It has been three years since he met Dina (Olivia Munn), an American reporter with whom he was once smitten. Their time together was cut short, and this will be the first he's seen of her since that idyllic moment. Jack and Dina will be seated together at a table of uniquely eccentric other guests. Unfortunately, events once again get in his way. Hayley's old flame, Marc (Jack Farthing), has crashed the wedding. Hayley is frantic, certain that Marc will stop at nothing to ruin her wedding and her marriage. She begs Jack to help her. If he would only put a few drops of a strong sedative in Marc's drink, the danger would be over. Reluctantly, Jack obliges, but when the table assignments are switched, the sedative ends up in the wrong stomach. Comic mayhem ensues.
