During World War II, a mild-mannered Slovaks carpenter Anton "Tóno" Brtko (Jozef Kroner) is offered the chance to take over the sewing notions store of an old, near-deaf Jewish woman Rozália Lautmannová (Ida Kaminska) as a part of the enactment of an Aryanization (Nazism) regulation in the town. As Tóno attempts to explain to Mrs. Lautmannová, who is oblivious of the world outside and generally confused, that he has come to be her supervisor and owner of the store, Imrich Kuchár (Martin Hollý, Sr.), a Slovak opponent of Aryanization, steps in and reveals to Brtko that the business itself is less than profitable, as Lautmannová herself relies on donations. The Jewish community then offers the amiable Brtko a weekly payment if he does not give up the store, which would otherwise be given to a new, possibly ruthless Aryanizer. Tóno accepts and lets Mrs. Lautmannová believe he is her nephew who has come to help in the store. Their relationship grows, until the authorities round up the town's entire Jewish population for transport, and Tóno finds himself conflicted as to whether he should turn in the senile Mrs. Lautmannová, or hide her. When the woman finally becomes aware of the "pogrom" all around her, she panics, and in attempting to silence her, Tóno accidentally kills her. The realization devastates him, and he hangs himself.
