Crime scene cleaning is the subject here, and the series follows a crew working the job in Toronto, mopping up after violence once the police tape comes down and the investigators leave. The pilot aired July 4, 2010, and one person handled the writing, directing, and camera work, giving the show a small, hands-on feel rather than a slick network gloss. The camera stays close to the physical work: scrubbing blood and tissue out of carpet, bagging contaminated material, disinfecting rooms that most people will never enter. Crew members talk through the practical side of the job, the chemicals, the protective gear, the paperwork, and also the toll of walking into someone's worst day for a living. It is a small, plainly shot look at a trade that exists because someone has to do it, told by the people who actually do.
