The film follows acclaimed composer and musician Max Richter and his creative partner, artist and BAFTA-winning filmmaker Yulia Mahr, as they navigate an ambitious performance of his celebrated eight-hour opus Sleep at an open-air concert in Los Angeles.

Emmy-nominated director Natalie Johns weaves in Mahr’s personal archive and performance footage from Berlin, Sydney, and Paris to create a rich portrait of a shared artistic process, along with contributions that illuminate both the science and story behind the work.
