Greetings again from the darkness. Filmmaker Rodrigo Sorogoyen begins his film with a long, slow pan shot across a deserted beach until we see the waves rhythmically rolling in and out. It appears to be a most peaceful setting, but instead it's actually the set up for one of the most intense and emotionally shattering short films ever.

Marta Nieto and her mother Blanca Apilanez are hanging around the apartment on what's a typical day for them. When Marta's answers a call, an unimaginable horror unfolds via cell phone. On the other end is her 6 year old son. He's on holiday with his father, Marta's ex. Only her son tells her, as his cell phone battery is dying, that dad left him and now he's alone on a beach ... he thinks it's France, but could be Spain.

Marta and her mother juggle cell phones as they try to track down the father, while keeping the young boy as calm as possible. It's a captivating and stunning performance by Marta Nieto, and a brilliant piece of filmmaking from Mr. Sorogoyen. It may be the most unsettling 19 minutes of movie I've seen, and if it had gone any longer, it might have become truly unbearable.
