Sundays on Leave

It is late in the Ceausescu era in Romania, and Cristina is having a difficult time with her boyfriend. He wants her to have *** with him before he goes off to do his obligatory stint in the army. She wants him to marry her first. She also gets involved with a slightly rebellious actor, a would-be ladies' man. He has some vague plans to defect - could those be the reason he is receiving mysterious phone calls? Or are they the work of his anonymous admirer?
