G.I. Joe: The Rise of Cobra

In the near future, weapons master James McCullen has created a nanotech-based weapon—nanomites designed to devour metal and other materials, capable of destroying anything from tanks to cities. The nanobots can only be stopped by activating the kill switch. His company M.A.R.S. sells four warheads to NATO, and NATO troops led by American soldiers Duke and Ripcord are asked to deliver the warheads. Their convoy is ambushed by the Baroness, whom Duke recognizes to be his ex-fiancée Ana Lewis. Duke and Ripcord are rescued by Scarlett, Snake Eyes, Breaker, and Heavy Duty. They take the warheads to The Pit, G.I. Joe's command center in Egypt, and upon arriving, rendezvous with the head of the G.I. Joe Team, General Hawk. Hawk takes command of the warheads and excuses Duke and Ripcord, only to be convinced to let them join his group, after Duke reveals that he knows the Baroness.
