Duncan McCue travels to Penelakut, an island off the coast of B.C., and the site of the Kuper Island Residential School. The community has torn down the reviled building, but the dark memories of what happened at the nearly-century old institution linger. Survivors James and Tony Charlie give a tour of their old school grounds, and we look into the mystery of what happened to one boy, Richard Thomas, who did not make it out alive.
