A sheriff goes out to investigate the death of his own wife, and stumbles across a handful of bullets that he believes can be used as evidence in our exclusive clip from the upcoming modern day Western drama Frontera. But a sudden gun blast reveals that there's more to this story than meets the eye. Ed Harris stars as Sheriff Roy, who discovers that a Mexican immigrant (Michael Peña) in the U.S. illegally may be responsible for his wife's demise. Check out this latest footage, along with the trailer, before seeing Frontera, in theaters and available on iTunes and VOD now.

Frontera follows the events that take place after a former Arizona sheriff's wife (Amy Madigan) is killed while riding on their ranch. It appears a Mexican man (Michael Peña) crossing in to the US illegally is at fault. As former Sheriff (Ed Harris) and current Sheriff (Aden Young) search for answers, lives are changed forever.
