Plot Summary:Season premiere. Car 27 stakes out a cockfighting ring. Cullen (Patrick Brammall) and Tolbeck (Tim Meadows) are rattled when a hero of the San Diego Police Department falls from grace. Both Marco (Jason Mantzoukas) and his new partner-in-crime, Frankie, have a secret. Fatima (Sunita Mani) falls victim to extortion. Jake Johnson and Cristin Milioti guest star.
Set against the world of a major drug cartel bust, the series follows two low-level cops who have spent far too much time in a car together; two criminals who are largely kept in the dark; two dispatch workers who haven't really clicked; and two Mexican tunnelers who are in way too small a space considering they've only just met.
