Plot Summary

Four strangers find themselves groggy and disoriented on a deserted island covered with surveillance cameras. Stripped of their belongings, they each hold a phone—blank, with no apps or signal. Suddenly, a message from a masked captor appears: they have 48 hours to figure out why they've been taken if they want to survive. To do so, they’ll be allowed two minutes of connexion at random intervals. But if they try to contact loved ones or alert the authorities, their mission ends, and they'll be executed.
