She pretended to be a nurse in Colorado, Ontario, Alberta and B.C., posed as a teacher in Alberta and Quebec and worked as a hairstylist in multiple cities.

And no matter how many times this serial imposter ends up behind bars, Brigitte Cleroux just keeps returning to her life of deception.

In the documentary, “The Professional,” Bethany Lindsay follows Cleroux as she zig-zags across North America, racking up criminal convictions along the way. Disturbed patients, a bullied former student and a whistleblowing nurse all share their experiences — and talk about the pain Cleroux caused them.

Every person who’s crossed paths with Cleroux has a very different story to tell, but they’ve all been left with the same question: Why does she keep doing this?
