The Sand (2015)

After an epic beach party in celebration of their college graduation, a large group of hung-over twenty-somethings wake up in a secluded private beach. But, under the bright light of an otherwise ordinary Spring-break morning, the unsuspecting teens realise that, somehow, the sand under their feet is alive, ready to devour those who touch it. Now, as the death toll keeps rising, an unseen carnivorous entity is waiting patiently for their slightest wrong move. Is there an escape from the killer beach?
