Inspired by the physicists who built the Soviet atomic bomb, the film DAU follows a brilliant Greek-born physicist from 1928 through four tumultuous decades in the USSR. Driven to uncover the laws of the universe, the idealistic Dau is drawn into state service to help create one of history’s deadliest weapons. Inside a secret research institute, life is governed by scientific ambition, power, surveillance and privilege. As his autonomy erodes, Dau seeks freedom beyond his marriage through a succession of affairs, gradually losing both himself and his capacity to love. At once an intimate portrait of a man in pursuit of happiness and freedom and a vast fresco of a society founded on violence and ideology, DAU traces the small compromises that shape a life and alter the course of history.

It is 1956. Dau is a distinguished Soviet scientist who meets up with the love of his youth – Maria, a Greek actress – during her three day visit to Moscow. They haven’t seen each other for 25 years. Dau is a successful and prosperous scientist, but feels excruciatingly dissatisfied with his family life. Through Maria he hopes to regain lost harmony and beauty, but reality intrudes when Nora, Dau’s wife, returns home.

Alienated from the rest of the scientific Institute in which they live, a lonely housewife and her teenage son break the ultimate taboo, with only their submissive maid to bear witness.

Natasha runs the canteen at a secret 1950s Soviet research institute. This is the beating heart of the DAU universe, everyone drops in here: the institute's employees, scientists and visiting foreign guests. Natasha's world is a small one, split between the demands of the canteen during the day and alcohol fuelled nights with her younger colleague Olga, during which the two confide their hopes of romance and for a different future. At a party one evening Natasha becomes close to a visiting French scientist Luc Bige and the two sleep together. The following day her life takes a dramatic turn when she is summoned to an interrogation by the KGB's General Vladimir Azhippo who questions the nature of her relationship with the foreign guest.

Katya, a young librarian, believes in love, but her ideals are crushed by reality. After a string of disappointing affairs, Katya finally finds tenderness and understanding in the arms of her colleague, a journalist called Tanya. But then the First Department interferes: the state security services see this relationship as unacceptable for a Soviet woman.

Two men and a woman happen to meet in a bar. We learn from their conversations both the intriguing and banal details of their lives. But is anyone really telling the truth?

Nikita Nekrasov is a scientist, a theoretical physicist who studies our world and other possible worlds. He refuses to make a choice between mathematics and physics, between one woman and another, as he ponders the existence of the multi-universe. At scientific conferences, attended by eminent foreign scientists and a rising younger generation of physicists alike, Nekrasov gets carried away debating the beauty of string theory. He attempts to explain to all of his women – Katya, the librarian, Zoya, the scientific secretary, Svetalana, the head of department – about the theory of his own polygamy, and the possibility of having enough feelings to satisfy everyone.

A mathematician in a secret Soviet research Institute believes that ayahuasca is the key to unlocking all the potential of the quantum universe, but its nightmarish visions also foreshadow his tragic demise.
