Note: The scenario and the killer change with each playthrough, making it random.

You receive a mysterious letter with no return address, leading you to a place that will force you to live your worst nightmare.

On the first night of your stay, your grandmother Estefania was the first to die at the hands of the killer. Now you must survive among the 13 (including yourself) remaining passengers and discover who the killer is before they find you.

Trapped with no way to communicate with the outside world for 13 days, everyone must come together before their life clock hits 0.

Will you find love? The power of friendship? Or something darker in all of this?
