A young woman is in love with a successful surgeon: a man torn between his love for her and his womanising. His mistress, a free-spirited artist, lives her life as a series of betrayals, while her other lover stands to lose everything because of his noble qualities. In a world where lives are shaped by choices and events, and everything occurs but once, existence seems to lose its substance and weight - and we feel 'the unbearable lightness of being'. Kundera's classic provoked a whole generation, encompassing passion and philosophy, body and soul, infidelity and ideas, the Prague Spring and modern America, political acts and private desires, comedy and tragedy - in fact, all of human existence.
