Plus One (2019)

Twenty somethings, Ben King and Alice Mori, who have close friends since college, reunite after a long time apart at the wedding of two mutual friends. Despite the happiness of the event, the two are both facing the toughest challenge either of them have ever faced: Summer; the season of weddings. Alice is dreading this, as she has been recently dumped by her longtime boyfriend and is now without a date to every wedding she is obliged to attend. For Ben, a half hopeful, half hopeless romantic, he's simply biding his time and complacently waiting for his perfect match to walk into his life, much to the displeasure of his friends, all of whom are pushing forward in life and getting married themselves, and especially his father, whose own wedding is fast approaching. With both of them needing to attend the weddings they're invited to, they agreed to be each others' plus one at each wedding to save face, ward off inquisitive friends, help Alice get over her ex's absence in her life and help Ben find his seemingly perfect match. However, across the summer; the two eventually realize that sometimes your permanent 'plus one' isn't the person whom you expect to find in life.
