MS1 is a maximum security space prison that is in an experimental phase. Some of the most dangerous criminals in the universe are held there: 500 inmates who are kept in an artificial sleep so as not to cause any trouble. Everything seems to be in order until a riot breaks out, everyone wakes up and it causes almost a war inside the prison. However, at that moment, the daughter of the President of the United States, Emilie Warnock (Maggie Grace, The Twilight Saga: Breaking Dawn Part I), is visiting aboard the station, so she will find herself in the middle of the violence unleashed. Emilie and the MS1 team will be kidnapped by the prisoners so the President (Peter Hudson) will decide to send in special action agent Snow (Guy Pearce, L.A. Confidential), a man accused of espionage crimes, with the only mission to save his daughter... even if everyone else dies. If he wants to be free, Snow will have to follow orders to the letter.
