What would you do if your best friend disappeared into thin air and no one in your town seemed to care? That's what Heidi (Bright actress Lucy Fry) is faced with when her gorgeous, enigmatic BFF Jane (Hobbs and Shaw's Eiza González [1]) vanishes while competing for a rodeo queen title in their small desert town in She's Missing, a new film from writer-director Alexandra McGuinness (Riders).

In our exclusive trailer for the harrowing drama, above, we see Heidi ignore warnings to stop looking for her friend, instead venturing into the precarious violence of the desert on the hunt to bring Jane home safe. Along the way, she digs up dangerous secrets and encounters a series of unusual men and women in her search for the truth.

In addition to González and Fry, Blake Berris, Sheila Vand, Christian Camargo, and Josh Hartnett [2] also star. Watch the trailer for She's Missing before it premieres on Dec. 20, and then check out the other new films that should be on your radar in the coming months.
