In the 1930s in rural Ontario, farmer Bill Reid buried the tombstones of a Black cemetery under a pile of broken rocks to make way for a potato patch. In the 1980s, descendants of the original settlers, Black and White, came together to restore the cemetery – but there were hidden truths no one wanted to discuss. Deep racial wounds were opened. Scenes of the cemetery excavation, interviews with residents and re-enactments – including one of a baseball game where a broken headstone is used for home plate – add to the film's emotional intensity. Speakers for the Dead reveals the turmoil stirred up by desecrated graves and underlines the hidden history of Blacks in Canada.
