Rhonda and Barbara 'Baby' Bird are half-sisters - and full partners in their Los Angeles detective agency. They agree on nothing. Rhonda, a former attorney, takes a by-the-book approach to solving crimes, while teenage Baby relies on her street smarts. But when they take a controversial case of a loner whose popular wife has gone missing, they're accused of being PIs who can't tell a client from a killer. The Bird sisters share a late father, but not much else - except their willingness to fight. Fight the system. Fight for the underdog. Fight for the truth. If they can stop fighting each other long enough to work together.
