The City of Toronto faces a historic downpour causing Gina's basement to flood with water from the City's sewage system backing into her home. When things seemed like they couldn’t get any worse, the remediation company hired by her insurance provider fails to follow the right protocols, putting Gina's son, Joey, at risk when he tries to clean up the mess himself. Mike arrives on site to tackle the flood-ruined basement with his team. When Mike learns that Joey's grandfather was a self-taught carpenter, and had a workshop in the basement, he does double-duty to not only restore this family's home, but the fond memories of a grandfather's love and true craftsmanship.
