CC Cilento’s best memories are of spending every summer holiday running wild in and out of the Friend family beach house with her cousins, James, Ollie, Felix and Lily. It’s the next best thing to having brothers and sisters. They’ve continued the summer tradition into adulthood, getting together at the shack with its absolute beach frontage.

But now a bombshell has dropped: the four sibling cousins have officially inherited the property – along with an unexpected fifth share to CC. What starts out as the perfect gift, and a way of keeping the family connected forever, quickly devolves into an emotional power struggle. Half of them want to keep the legacy intact, while the others want to sell – and each side will do anything to make it happen. Soon, CC can’t tell friend from foe. When a body is found on the shack’s beach, has this family dispute turned deadly?
