It's a perfect beach day, or so thought a family, a young couple, a few tourists, and a refugee. All of them end up in the same secluded, idyllic cove filled with rock pools and sandy shore, encircled by green, densely vegetated cliffs. But all is not as it seems; this utopia hides a dark secret. First, there is the dead body of a woman found floating in the crystal-clear water. Then, there is the odd fact that all the children are aging rapidly. Soon everybody is growing older every half hour and there doesn't seem to be any way to escape the cove. Based on the graphic novel 'Sandcastle' (2013) by Pierre Oscar Levy.
