As newly promoted Col. Johnny Rico (Casper Van Dien) returns to military service, political unrest brings the planet of Roku San to a breaking point. When Rico steps in to protect a farmer from a fellow soldier's violent outburst, he finds himself scheduled for execution. But Rico's life is spared when the Federation taps him to lead a secret mission, sending him on a collision course with the site of a new "bug" invasion -- and his old flame, Capt. Lola Beck (Jolene Blalock).
