It chronicles the story of two resistance members who are compelled to assume the roles of husband and wife in order to evade detection by the Nazis, despite being married to others.
[3] During the closing stages of World War II, amidst the siege of Budapest, Kata (Ildikó Bánsági) is intercepted on her way home from the cinema and informed that her apartment is being searched.
With false papers under the alias Mrs. János Bíró, she seeks refuge in a suburban house alongside her "husband" (Péter Andorai), a prominent figure in the resistance movement.
In their shared quarters, János treats Kata with aloofness, outlining the rules of hiding: she mustn't leave without his consent and is forbidden from divulging personal information.
Meanwhile, János gradually overcomes his fear and paranoia, only to realize his love for Kata when it's too late, as his actions have irreparably damaged their relationship.
