Paul (Marlon Brando), a middle-aged American hotel owner mourning his wife's suicide, meets a young, engaged Parisian woman named Jeanne (Maria Schneider) at an apartment that both are interested in renting. Paul takes the apartment after they begin an anonymous sexual relationship there. He insists that neither of them must share any personal information, even given names. The affair continues until one day, Jeanne arrives at the apartment and finds that Paul has packed up and left without warning.
Paul later meets Jeanne on the street and says he wants to renew the relationship. He tells her of the recent tragedy of his wife. As he tells his life story, they walk into a tango bar, where he continues telling her about himself. The loss of anonymity disillusions Jeanne about their relationship. She tells Paul she does not want to see him again. Paul, not wanting to let Jeanne go, chases her back to her apartment, where he tells her he loves her and wants to know her name.
Jeanne takes a gun from a drawer. She tells Paul her name and shoots him. Paul staggers out onto the balcony, mortally wounded, and collapses. As Paul dies, a dazed Jeanne mutters to herself that he was just a stranger who tried to rape her and she did not know who he was, as if in a rehearsal, preparing herself for questioning by the police.

Answer: At a tango bar.
