Lesha is ready to be with Dasha in joy and in sorrow, in wealth and in poverty, but not in illness... When a close friend betrayed her secret, when her own parents recoiled from her like a leper, who will condemn him? after all, they could live together happily ever after or die on the same day - die then, on a fog-shrouded highway. That day, Dasha, a selfless young nurse, bleeding herself, got out of the Zhiguli car that had been mangled in the accident to provide help to those who needed it. That's how she got infected. Dasha doesn’t know how, but she must move on!
