Heiress Evelyn Hart is pushed off a cliff by her husband Adrian and his mistress — but she wakes up three years earlier, on the morning she signs her divorce papers. This time, she picks up the pen first.
After signing, she returns to the old apartment her mother left her twenty years ago. Inside a dust-covered iron box she finds three relics: a watch stopped at the hour her mother died, a photograph from when she was five, and a safe-deposit key.
Beneath them lies a document locked away for twenty years, bearing her own name. Her mother's "accident" was never an accident. With the help of Julian, her childhood friend, she unearths the forged signatures, the stolen name, the recording and the letter, piece by piece.
She walks into the boardroom with her evidence, takes the head seat, and pulls Adrian down from his chair of power. In the end, it is he who kneels before her, signing his own end with the same pen he once used to take it all. One life ended on a cliff. This one starts from the top floor.
