The show is about Team One of the Metropolitan Police's Strategic Response Unit, a fictional police tactical unit.
Flashpoint follows a fictional police tactical unit in an unnamed North American metropolis. The SRU is tasked with resolving high-risk situations that regular police units are not capable of effectively handling. The initiation of a given situation is often determined by a split-second decision, hence the show's title.
