In London, an award-winning film-maker documents her best friend's journey into an assisted marriage in line with his family's Pakistani heritage. In the process, she challenges her own attitude towards relationships.

How do you find lasting love in today's world? For documentary-maker and dating app addict Zoe (Lily James), swiping right has only delivered an endless stream of Mr. Wrongs to her eccentric mother Cath's (Emma Thompson) dismay. For Zoe's childhood friend and neighbor Kaz (Shazad Latif), the answer is to follow his parents' example and opt for an arranged (or "assisted") marriage to a bright and beautiful bride from Pakistan. As Zoe films his hopeful journey from London to Lahore to marry a stranger chosen by his parents, she begins to wonder if she might have something to learn from a profoundly different approach to finding love.
