Carlos is working undercover to get an elusive drug dealer known as El Vaquero. He has gained the confidence of his number two, Johnny Primo. Walker wants them to bust Johnny and maybe he can lead them to El Vaquero. But Carlos wants to stay undercover because it seems that El Vaquero killed Carlos' brother, who was an addict/dealer who wanted to quit but died of an overdose. Carlos thinks El Vaquero had him killed. Walker says okay but Johnny learns that Carlos is a cop and grabs and beats him up to know what he has told.
