The basic premise is that they show the 'flashpoint' of a situation, a brief glimpse at a volatile situation. This teaser provides a context for the story telling that comes afterward as a depiction of the various events that led to the situation, and then goes to resolve the issue.
I really, really enjoy this show. Working in Toronto, I enjoy seeing some of the same places that I travel to in this show. The 'shades of grey' antagonists, the not quite impenetrable armour of the protagonists and the fact that there are unexpected twists to the stories makes for some great watching. Unlike some of the other shows, where you get into a "Oh, we're getting near the commercial, he's going to puke / crash / seize" routine, the show has managed to use believable twists and character development to surprise, despite the 'spoiler' that begins each show.
I sincerely hope that there are many seasons to come, and that it will continue to develop the characters and story lines behind them. Kudos to the wonderful cast for their great performances, and to a show based in Canada that doesn't look like it was crafted on a shoe string budget.
