This plodding romantic drama concerns two people trying to cope with the political changes in post-Franco Spain. Begona (Angeli Van Os) is a beautiful law professor who meets the prosperous government official Juan (Didier Flamand) at a left-wing political rally. He pursues her, and Begonia eventually falls for Juan. Heated political discussions always precede their passionate love making. A government agent with a compromising picture of the amorous duo convinces Juan that Begona is a KGB agent, and Juan is blackmailed into negotiating with Basque terrorists with headquarters in Paris and Brussels. Juan discovers he has been fooled when his Basque contact is assassinated. Unsure if she is really a spy, Juan prepares to sacrifice everything for love. Begona is slowly drawn to the prosperous comfortable lifestyle that Juan can afford and fears she is losing her political passion.
