Diplomatic Siege is a 1999 American direct-to-video action film directed by Gustavo Graef-Marino and starring Peter Weller, Daryl Hannah and Tom Berenger.
[1][2] When Steve Mitchell is covertly dispatched to the US embassy in Bucharest, Romania, to neutralize a long-undetected nuclear device left there since the Cold War's conclusion, he finds himself entangled in unforeseen complications.
Teaming up with Erica Long, a diplomatic attaché whose true identity remains obscured, they must collaborate to input the correct computer code, deactivating the weapon and fulfilling the mission.
With time running out, the Pentagon's Joint Chiefs of Staff dispatch General Swain to quell the deadly siege and avert the looming threat of a nuclear detonation.
"[1] TV Guide gave a mixed review: "This far-fetched cold war thriller would've been more fun to watch had its creative personnel taken a more intentional tongue-in-cheek approach; as it is, the stars veer over the top whenever the action flags, but this comic attack seems less a desire to kid the material than an attempt to camouflage its weaknesses.
