Not realizing that they have both been sent undercover by their respective government agencies to bust the same Mexican drug lord –– a black hat called Papi Greco (Edward James Olmos) –– Bobby and Stig naturally mistake each other for real criminals. Though pretending to be partners for the time being, both take it for granted that the other will be trapped –– quite deservedly –– in the sting that fells Greco.
No sooner is this mix-up resolved than a whole series of corruption-driven complications follows in its wake. Most of these involve yet more federal employees: Bobby's colleague — and, as we're shown, his on-again-off-again lover –– Deb Rees (Paula Patton), Stig's boss Quince (James Marsden) and a tough-as-nails political wire-puller known only as Earl (Bill Paxton).
Since many of the circumstances are too farfetched to bear scrutiny, moviegoers' reactions will largely depend on their taste for implausible –– but occasionally giddy and amusing –– plot developments.
The arc of events leads predictably toward the formation of a bond between the main characters. Their friendship is forged, however, against a gritty background, one that presents us with scenes of torture as well as with the fleeting sight of a severed head.
As a result of their dealings with Greco, at one point Bobby and Stig are forced to make their way back north of the border in the company of a group of undocumented immigrants who are being guided by so-called coyotes. Though the incident is not without its ironic impact, any sober-minded effect is more than a little undermined by the fact that Stig treats the journey, at least in retrospect, as something of a lark.
