Hoping for fast cash, David (Benjamin Walker), George (Brian J. Smith) and Greg (Victor Rasuk) -- friends whose high school pastime was chasing illegals back across the Texas-Mexico border -- steal a rig from David's father, Slater (Peter Gallagher). But the illegal cargo proves more alarming than stolen TVs. As their plan falls apart and truths come to light, the guys find themselves as vulnerable as the migrants they had chased at the border.
