Two first-timers you’ll be hearing a lot more from: writer/helmer Joshua Marston and his leading lady Catalina Sandino Moreno, who snagged an Oscar nom for this visceral drug-mule drama. Marston lenses his taut script in a white-knuckle docu-thriller style, following desperate teen Maria (Moreno) from Bogota to the Big Apple with a tummy full of smack pellets. The detail’s graphic but not gratuitous and you won’t catch Marston with any easy answers or pat morals in his possession. Moreno, meanwhile, nails it with an unaffected combo of resilience and vulnerability. The storytelling gets the shakes in the last quarter but this is still Class A.
