I seen a trailer for this 2 maybe 3 years ago. Teenagers are placed on a dangerous planet for a type of coming of age competition. They have to find some type of object, some will die on this Journey and no one can go home until someone finds the object. I had forgotten about this movie until hunger games came about and reminded me about it. I can't remember the name to this movie or even if it came out, can anyone help please? I believe the name started with a S and it was a foreign maybe Spanish film.
