In winter of 1901, a love struck and pregnant Mileva returns to her family home in Titel to give birth to an illegitimate child of her lover and colleague Albert Einstein. A few weeks later, she returns to Zurich. Without a child. Mileva and Albert marry.
Four years later, in 1905, Mileva, Albert and their newborn son Hans-Albert live modestly and happily in Bern, Switzerland. They work together but the papers somehow get published only under Albert’s name. After a visit from Pierre and Marie Curie, and a surprising publishing of Albert’s paper based on her personal notes, Mileva realizes she cannot fight for the scientific recognition she deserves and keep her perfect family intact. She chooses family.
Growing more popular and busy with work and social life, Albert starts an affair with his cousin Elsa. Mileva keeps getting on his nerves and one night, after a particularly bad argument, Albert sets a very strict set of rules for her to follow. She gets pregnant and has another son, Eduard (Tete). Despite her wish and effort to keep the family together, Mileva is forced to leave Albert. She takes her children to Titel which is engulfed in battles of World War One. When she recieves a telegraph from Albert asking her for a divorce, Mileva has a nervous breakdown. After being discharged from a mental hospital in Zurich, Mileva returns alone to her parents in Titel. Wanting to cheer her up, her father takes her to a student suffragette protest at the University of Belgrade. This gives her the strength for one last, most important fight – for her children, her self and her dignity.
With some help from her old friends, Mileva unofficially retakes and passes the exam that she failed twice when she first got pregnant. But Albert insist she takes him back. He is convincing and for a moment Mileva hesitates, but ultimately she asks him for a divorce. She reminds him of all they used to share together – love and notes alike. Finally, Mileva gets custody of her two sons, a divorce and the monetary portion of Albert’s future Nobel Prize.
