In 2079,
CIA operative Snow is arrested for murdering Colonel Frank Armstrong, who had uncovered evidence of a
mole selling secrets about the United States space program.
Secret Service Director Scott Langral, on advice from the President, has Snow convicted of murder and
espionage, despite Snow protesting that he was helping Armstrong discover the mole. Snow is sentenced to thirty years in the maximum security space penitentiary
MS One, where prisoners are kept in
stasis for the length of their sentences. Snow's friend and fellow agent Harry Shaw tries to locate Snow's contact Mace, who knows where Frank's briefcase containing the stolen secrets is hidden. Meanwhile, the President's daughter Emilie arrives on
MS One to investigate claims that keeping prisoners in stasis can cause them to develop
mental instability. The warden allows her to interview Hydell, a deranged prisoner. He manages to escape and releases all of the prisoners, starting a riot led by his brother Alex. Emilie is shot and is captured along with others. Shaw convinces Langral and the President to send Snow to rescue Emilie rather than risk her life in a
siege. Snow is initially reluctant to go but agrees after Shaw tells him that Mace is on
MS One and could help Snow prove his innocence. Langral initially attempts to trick Alex into releasing Emilie, but Hydell disagrees and kills a hostage negotiator, forcing Snow to infiltrate
MS One. Alex realizes that Emilie is the President's daughter, but she escapes with her bodyguard, Hock, and they hide in a secure room. A problem with the
oxygen supply force Hock to commit
suicide to buy Emilie more time. Snow breaks into the secure room and rescues Emilie after administering first aid. Snow then changes Emilie's hair & clothing to conceal her gender, allowing them to walk through the prison population without being noticed. They find Mace, but the stasis has given him
dementia and made him incoherent. Snow and Emilie bring Mace with them and attempt to reach the
escape pod. With no one at the helm, the prison falls out of orbit and crashes into the
International Space Station. The collision causes a hull breach, killing Mace. Snow brings Emilie to the escape pod but discovers it has only one seat. Realizing that he has been sent there to die, he sends Emilie on her way, but she allows the pod to launch without her because she believes the remaining hostages will be killed. Hydell contacts Emilie and threatens the hostages unless she reveals her location; after she does, he kills them anyway. Snow and Emilie discover evidence that the prisoners were being illegally used as test subjects. Alex finds and captures Emilie; he also shoots Snow, leaving him for dead. Alex learns that Hydell has killed all of the hostages; he contacts the President, threatening to let Hydell and the prisoners
rape Emilie if they are not released. The President refuses to allow a siege and risk Emilie, causing Langral to
temporarily relieve him of his command. Langral orders the destruction of
MS One. Hydell tries to rape Emilie but is stopped by Alex; Hydell kills him, then tries to stab Emilie, but Snow arrives and knocks him out. Snow and Emilie flee from Hydell and the remaining prisoners. Meanwhile, Langral's men attack the prison and manage to plant a bomb to destroy it. Snow and Emilie use space suits and jump from
MS One as it detonates. Using their suits, Snow and Emilie re-enter Earth's atmosphere and land safely in
New York City, where Snow is arrested. Emilie later realizes that Mace's incoherent rambling was actually a code revealing the location of Frank's briefcase. Examining the motel room where Frank was killed, Emilie realizes that Langral saw what he believed was Snow shooting Frank on a mirrored door, which only showed part of what happened; in reality, Snow was shooting at the actual assassin at the same time that Frank was shot. In an interrogation room, Snow gives the briefcase to Shaw, who unlocks it but is shocked to find it empty. Snow notes that he had not given Shaw the combination, and Shaw is revealed to be the mole and arrested. Snow is released, and his possessions are returned, including a lighter given to him by Frank before his death. Examining the lighter, Snow finds a
memory card containing the real secret information hidden inside. Emilie meets Snow and teases him after discovering his first name is Marion; the pair walk away together. ==Cast==
