When aspiring stage-manager Rebecca Weir falls for the married director of SenseInSound theatre company, she initiates a love triangle and working collaboration which go on for two decades. Set in Toronto at the start of the 1980s, You’ll Know Even Then explores the genesis of what its disciples call ‘The Work’. The director, Marlin, has the status of a Guru in SenseInSound, but is he pushing people’s limits or abusing his power? Is the ‘The Work’ a cutting-edge artistic practice, a road to personal healing, or a cult?
