Alta Mar plot
A grand transatlantic ship brimming with passengers is en route from Europe to South America in search of a brighter future. On board are the two sisters Carolina and Eva, who are as different as they are inseparable, and a handsome officer, Nicolás Sala, who has misplaced fate. There is a mystery to be solved: the murder of a passenger whose name is not on the passenger list and whom no one remembers. Love, intrigue and many lies... in a ship that hides a story in each of its cabins and a dark secret deep inside. Only one thing is clear: the killer cannot leave the ship.
