In order to get closer to their ultimate mark, the head of a notorious Mexican drug cartel, Carter has to pose as a porn king looking to expand his business into pharmaceuticals.

When the team infiltrates a local casino to investigate the disappearance and presumed murder of a law-school student with a gambling problem, the case has a negative effect on Ty who runs with his high-rolling cover a little too far. Meanwhile, Alex gives Jaimie a hard time over the risks she is willing to take with their target, a no-excuses loan shark.

In order to locate an infamous anti-government militia leader, the team stages a jail break for his younger brother in the hope that he’ll lead them to their target before he assassinates a prominent Federal Judge.

Jaimie poses as a junkie in order to infiltrate a dangerous crew of thieves who pose as DEA agents in order to steal from drug dealers. As Carter grows concerned about Jaimie’s eagerness to make the case, Ty and Dean are stuck with a loveable yet annoying informant who wants nothing more than to be a cop, just like them.

The team goes after a home invasion crew with Alex and Carter acting as the bait.

After a young black man is gunned down, evidence points to the possible corruption of a noted figure in the black community; Ty dates a woman with a connection to the shooting.

Carter, Dean and Jaimie go undercover to corner two drug-smuggling brothers who use a flower-import business as a cover for their activities.

Meanwhile, Dean asks Jaimie out on a proper date just; Ty has second thoughts about his impending divorce; and Carter for a major life change.

The team keeps trying to infiltrate the drug-smuggling ring in order to get to a terrorist. Meanwhile, Alex is offered a promotion in Miami and Ty keeps struggling with his divorce.
