Malgorzata beheerst elk aspect van haar leven. Ze staat met beide voeten op de grond, is vastberaden en goed georganiseerd. Ze wijdt alles aan haar carrière. Haar jongere zus Lucja is haar tegenpool - spontaan, altijd op zoek, soms verdwaald. Ze ontplooit zichzelf als moeder. Hoewel hun levenspaden vaak in verschillende richtingen liepen, verstrengelen ze zich vandaag tijdens de belangrijkste reis. Malgorzata is terminaal ziek en Lucja moet haar naar een gerenommeerde kliniek in Zwitserland brengen.
Nee, helaas is Lęk nog niet beschikbaar op Netflix in Nederland.
