Kati has had the man of her dreams at home for five years: attractive, loyal and a successful doctor. Unfortunately, "her" Felix now spends so much time working in the hospital that Kati often feels alone. When she meets the handsome, charming artist Mathias, she feels the same way Felix did. Unfortunately, without breaking her husband's heart, a new beginning is unfortunately not possible. Shortly before her last inhibitions fall, fate shuffles the cards in an incredible way: After a car accident, Kati wakes up in the past - exactly on the day five years ago when she accidentally met Felix. Kati wants to use the unexpected second chance and finds Mathias, who falls in love with her this time too. She tries to avoid meeting Felix, but somehow it doesn't work. He keeps bumping into her and is just as beguiling as the first time. Now she has to pull herself together with Felix. When Kati finds out that his girlfriend Lilian is cheating on him with his best friend Gereon, she interferes in Felix's life.
