In 1974, Jimmy Connors was the greatest tennis player on Earth. In 1991, he's getting annihilated at the US Open by his arch-nemesis' little brother. What happened next was one of the greatest comebacks in sport, when Jimmy, fuelled by ghosts of his turbulent past, winds back the clock to remind the world what happens when you rattle the cage of a geriatric tiger, one last time. Edinburgh Comedy Award Winner Adam Riches (***** (Independent)) makes his Summerhall debut with this fast-paced, funny and intensely physical ride, deep inside the mind of an ageing, swaggering alpha.
