Suspects is a British cop procedural drama; series one and two come in the same case. "Filmed from an eye witness perspective," it also features improvised dialogue. The latter makes the show feel like a reality TV show except it does not have in camera confessionals. It's a gritty, realistic series that features brutal crimes; and, due to its improvised dialogue and eye witness perspective, it feels quite different from scripted dramas.
The show follows three detectives: Detective Inspector Martha Bellamy, Detective Sergeant Jack Weston, and Detective Constable Charlie Steele. In the first season each episode is treated as a stand-alone in that a different case is solved in each episode, and there's no spillover of storylines across episodes. The second season solves two crimes; each crime spans two episodes. I've read that seasons three and four return to a format similar to season one.
It's interesting to me that Weston, the sole male on the team, routinely allows his emotions and personal biases to affect his professional perspective on a case or a potential suspect. In one instance it's to the detriment of a case and leads to a month long "vacation" (a.k.a. unofficial suspension). Weston often appears with disheveled hair, and he is the resident hot head. Steele and Bellamy are much more measured, level headed, and do not allow personal issues to affect their professionalism on the job.
