Initially posted by Twitch and then by Badass Digest‘s Devin Faraci, this trailer for Jaime Osorio Marquez‘s The Squad (El Paramo) indicates an above-average ride. The Columbian-made thriller will open sometime in 2012. It may not be fully finished, which would be an acceptable reason why it’s not playing at the Toronto Film Festival.

“All contact with a military base high in the desolate wastelands of Colombia has

been lost,” the synopsis reads. “The authorities — believing the base to have fallen to a terrorist attack — send a nine-man squad to investigate. When they arrive, the men discover a shocking scene of carnage, and only one survivor — a mute woman in chains.

“Gradually the isolation, the inability to communicate with the outside worldand the impossibility of escape begin to undermine the sanity of the soldiers.They start to question the identity of their enemy, and the true nature of the strange, silent woman. Is she a terrorist? A victim? Or something mores sinister? Something supernatural…?

“Paranoia takes root. Prisoners of fear and the terrible secret they share, their humanity abandoned, the men turn savagely on each other.”
