Molécule

A meeting of two world famous climbers, one an experienced mountaineer the other a sport climber, and a journalist (Ivan) results in a bet on which of the two is the best climber. Roger (the mountaineering expert) states that Martin (the sport climber) wouldn't survive a day on a 'real' climbing expedition, although he is considered to be the world's best sport climber (having just won an indoor 'world championship,' an event depicted in the opening scene). They plan to climb 'Cerro Torre,' in the Patagonia region of South America, near the Argentinian/Chilean border, one of the world's most difficult mountains, especially considering the extreme weather conditions common to the area.

In the winter of 1943 two young Jews, Alek and Fryda, escape, via sewer tunnels, from the atrocities underway in Warsaw ghetto. Alek, entrusted with undeveloped photos of the horrors within, makes his way to a supposedly safe apartment only to find it occupied by Germans. Another tenant, a pole Stephania, abruptly offers to shelter him in her spacious apartment. She comforts him and they make love that very night. Stefania is uncommonly generous and willing to jeopardize her own safety by hiding a Jew. She even goes to a nearby church and rescues Fryda. But Fryda is ungrateful and proceeds to sabotage the trio's safety in insidious ways.
