Bordertown: Laredo

Sifuentes orders Roly to go undercover to nab a top cocaine and heroin dealer--a dangerous assignment because the suspect's most recent crime involved shooting an officer.

With a big cartel shipment of heroin about to arrive in Laredo, the LPD team conducts a citywide crackdown of suspected heroin dealers to squeeze information out of them about where and when the drugs will arrive.

Sifuentes and Roly are determined to take down Quack, one of Laredo's most notorious heroin dealers. But it won't be easy--Quack has ducked the LPD's attempts to stop him twice before.

The team's K-9 sniffs out a package containing black tar heroin hidden in a child's teddy bear. Linking the parcel with a residence called the "Spiderhouse," the LPD hopes it will lead them to the distributor of the deadly form of heroin.

The seizure of 350 pounds of marijuana leads the narcotics unit to track down a similar-sized or sister load coming from Mexico. The trail leads to a truck stop where they discover a security guard brokering the deals.

Through information from a trusted C.I., LPD Narcotics busts a stash house holding cocaine and guns, plus a ledger filled with information that could help them put a heavy cocaine operation out of business.

After the murder of an ICE agent in Mexico, Sifuentes is determined to hit the cartels where it hurts, and a local casino's connection to a prostitution ring may give him the chance he needs.

A new confidential informant is willing to risk his life to give up vital information about dealers in exchange for help with his legal troubles. But when he tips the team off to a large shipment of meth, they can't be sure they can trust him.

A series of controlled buys leads Roly and his C.I. to the home of a local dealer. The SWAT team swoops in, but finds the house empty. They decide to call the bust off before suddenly spotting a car fleeing the scene.
