Triplicity

One week on an Alaskan cruise, three teens, and an endless trail of lies.
Enter a series of thefts on board and they all fall under scrutiny. Though Navy acts a proper preacher's daughter, she did end up with someone else's purse in her hands, and Jesse knows way more than he should about what's gone missing. Isaiah, however, is the one with motive-enough money and he could get back to his ranch. Each holds a piece of the truth, but exposing the thief could damn them all. They must navigate through the lies they've told, choose between standing together or saving themselves, and decide if innocence is worth facing their ugliest secrets.
