Gael García Bernal watches helplessly as his friends get shot in the first trailer for Jonás Cuarón’s chase thriller “Desierto.”

Bernal and Alondra Hidalgo star as undocumented Mexican workers pursued in the open desert by a shotgun-toting vigilante played Jeffrey Dean Morgan, who growls “welcome to the land of the free” after shooting several victims.

In addition to using the firearm, Morgan’s maniacal character also employs a well-trained German Shepherd to hunt down his prey.

Cuarón also produced the movie, along with his father Alfonso Cuarón, uncle Carlos Cuarón, Alex García and Charles Gillibert. “Desierto” premiered in the special presentations section of the Toronto International Film Festival and won the International Federation of Film Critics (FIPRESCI) prize.

The film from STX Entertainment hits theaters on March 4.
