Synopsis: On a rainy summer day in 1917, beloved Canadian painter Tom Thomson paddled alone onto Canoe Lake in Ontario's Algonquin Park and was never again seen alive. He was just 39 and had painted only 50 major works. In the decades following, this small but extraordinary body of work became the single most infuential in Canadian landscape painting and Thomson would grow into a figure of mythical proportions. For 50 years, new evidence and testimony continued to surface in his mysterious death.
