This watchable and well-made feature debut by American independent writer-director Joshua Marston is also very much a showcase for Catalina Sadino Moreno, who plays the eponymous lead with grit and energy. Maria is a fearless and attractive 17-year-old Colombian who leaves her job on a rose plantation to work as a drug mule. For $5,000 she swallows more than 60 rubber pellets of heroin, to be reclaimed from her stool after flying to New Jersey; should a pellet break internally, death will quickly ensue. The depiction of her risky voyage and what happens afterward is highly suspenseful and entirely believable. R, 101 min. Century 12 and CineArts 6, Pipers Alley.
