Sets (1968)

During the summer of 1937, Emanuel, a young man in his early twenties, is committed to a sanatorium on the Black Sea coast for treatment of his bone tuberculosis. The treatment consists of painful spine punctures that confine him to a plaster on a stretcher-bed. Little by little, as Emanuel gets accustomed to the sadness of his new life, he discovers that inside the sanatorium there is still a life to be lived to the fullest.

In this farcical dark comedy/melodrama, Lena manages to lose her place at college by virtue of throwing a minor hissy-fit when she catches her erstwhile boyfriend in bed with another girl. Instead of penalizing the boy for his behavior, Lena gets stuck with a court appearance and must pay a small fine, in addition to losing a boyfriend, her college career, and an apartment. Lena belongs to a film club which occasionally hands out awards, and the membership of it decides to send her into the Russian hinterlands to hand out an award to an obscure filmmaker. Throughout the film, Lena has been associated with a bizarre con man named Stepanych who, when his cons fall through, comes to her in the distant town she has gone to seeking her help in committing suicide.

Scuba-diver turned beach-bum Jonathan Slade is forced back into his previous milieu - the world of international espionage - in order to retrieve Black Boxes from an American jetliner that crashed under mysterious circumstances into the Black Sea. With his computer-hacker younger brother, Slade travels to a resort on the Russian-Turkish border to begin his quest. To his surprise and dismay, he's now joined by another secret agent, a beautiful but highly-skilled woman named Alex. As they begin diving in search of the downed jetliner, Slade and Alex begin to suspect they're being manipulated by higher-ups who may not be committed to American interests.

Along the Black Sea coast, we see a man and a woman arguing. They are apparently vacationers. Before long, the man has gotten back into their car and driven off, stranding the woman in a remote area. She hitches a ride with a delivery truck driver. At one of his stops, she gets off his truck to go to get some water. When the driver comes back to his truck and sees her gone, he assumes she has found another ride, and leave her. Once again, she is stranded. This time, the location is a lighthouse. She and the keeper have no recourse but to become acquainted, and for the next few days, that is what they do. Eventually, the man who left her in the lurch comes back to look for her, and finds her at the lighthouse.
