Fortress 1

Robert is a retired CIA agent living out his days in a high-tech, top-secret retirement resort for former intelligence officers. His peaceful seclusion is shattered when his estranged son, Paul, arrives for a visit, inadvertently leading a group of bloodthirsty mercenaries to the gates. Led by the vengeful Balzary, the criminals breach the compound to settle an old score, forcing father and son to retreat into a high-tech bunker known as "The Fortress." Inside the steel-walled sanctuary, they must utilize advanced weaponry and Robert's old combat skills to survive the relentless siege.
