Frontline starts with Lt. Jimmy Patterson storming Omaha Beach as a part of Operation Overlord, after which the OSS (Office of Strategic Services) sends him to disrupt German U-boat operations. The OSS discovers that the Germans are building a secret weapon, but their contact in the Dutch Resistance goes missing. As a result, Lt. Patterson joins up with the 82nd Airborne during Operation Market Garden to find him. After finding the contact and rescuing him from German custody, the OSS learns that the secret weapon is a highly advanced jet fighter called HO-IX. Lt. Patterson embarks to destroy the aircraft, however en route he has to cross the Nijmegen Bridge, disarm explosives, and send supplies to the British 1st Airborne in Arnhem. The OSS track down the man in charge of building the fighter (an SS officer called Sturmgeist). Lt. Patterson is sent to Emmerich to track Sturmgeist, but once aboard the SS Officer's personal train, Patterson is unable to catch him before he is able to escape. Even though the man-hunt for Sturmgeist was fruitless, Lt. Patterson manages to destroy a vital German supplies cache. Lt. Patterson infiltrates the secret airfield outside Gotha where the fighter is held, cripples German aircraft production, fights and kills Sturmgeist, and escapes the airfield using the HO-IX.
