Links exist, preying on humanity, and for some reason, like to inhabit Chicago.
The police department of this city has a special undercover unit to deal with the links. This is the premise of a new Fantasy TV series, Special Unit 2, which debuted on UPN recently. The first episode starts with a woman officer, Kate, trying to save a young girl from a gargoyle. Considered unstable by her superiors, Kate is in jeopardy of losing her job. That is when she meets Nick O Malley, an officer who tells her about Special Unit 2.
