Counterstrike (1990) : 3x4

A former KGB agent, Monica Steile, and her boyfriend, Gorki, smuggled a Soviet (or Russian) nuclear missile into Paris after killing two Russian border guards. Clark from the US State Department flies to Paris to tell Alexander and the Counterstrike team what has transpired, reminding them that any premature leaks to the press would cause panic in the Western world. At the same time, Steile has no intention of selling the missile to her client, instead she kills him and her boyfriend leaving their corpses at the scene of the supposed meeting. She and her lesbian girlfriend has other plans for the missile and the Counterstrike team now has to foil those plans after being caught behind the eight-ball.
