Gristle's Peak (2018)

On an August morning in 1712 three pirates (two men and a lady) murdered their captain. As punishment, they're marooned on the cove at Gristle's Peak, at the end of the known world. One pistol, with one shot, is left to them. As the day unfolds their rivalries, erotic shiftings, and at least one character's madness emerge. Who can live till morning, on the dreaded Gristle's Peak?
