A short line of code on a computer screen that Alex Peyton accidentally discovers turns out to be the number of a Jewish family's bank account opened at the beginning of World War II. This discovery dramatically changes Alex's life. The mysterious account is a trustee account, so the Nazis were unable to find out the name of the real owner of the money. Having been in a Swiss bank for more than half a century, the account has grown to a huge amount. In search of clues to the fate of the Jewish family, Alex plunges into the abyss of corruption and betrayal. With every step of the investigation, she, without knowing it, exposes herself and her heirs to danger - the danger of revealing a secret that could cost their lives.
