Two low-level cops who have spent too much time in a car; two criminals who are kept in the dark; two dispatch workers who haven't really clicked; and two Mexican tunnelers who are in a small space considering they've only just met.

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.
