To say that the lives of the Knight family revolves around wrestling would be an understatement. Ricky (Nick Frost) and Julia (Lena Headey) run a local gym where they teach classes and host matches in their working-class British town of Norwich. They’ve since passed their obsession onto their kids, including Raya (Florence Pugh) and Zak (Jack Lowden), who find their bonds tested when the WWE – the pinnacle of professional wrestling – arrives in London to host tryouts.

British actor/comedian Stephen Merchant writes and directs this triumphant (and true) underdog story, packing it with plenty of heart and relatability – regardless of whether you enjoy watching grown men and women rolling around in tights.

It sounds like the plot of a young adult novel: a set of identical triplets are adopted by three very different families, each unaware their new baby is one of three, until the brothers accidentally meet at university. This is in fact the remarkably true story of Edward Galland, David Kellman and Robert Shafran, whose reunion made global headlines in 1980.

In the years that followed their story took a darker turn as the brothers learned of the circumstances behind their separation, and struggled to deal with its impact. This highly acclaimed documentary explores not only scientific questions, such as the impact of nature versus nurture, but also ethical ones.
