This is a show about a rookie on the L.A. Sheriff squad. Only it’s a version of L.A. where a bunch of interesting things happen to a rookie on the first day. And most of them aren’t believable. And most of them aren’t actually interesting, come to think of it. It’s a trie version of cop work, and there’s nothing really going for it.
