Directed by Ulli Baumann, this German romantic drama explores a high-stakes emotional minefield that tests the limits of lifelong loyalty. The story follows Karen (Suzan Anbeh), a wine dealer who has been married to Paul (David C. Bunners), a successful defense lawyer, for over ten years. Though their marriage is stable, the passion has faded, and they face quiet domestic friction over Paul's strong desire to have children. Karen's life completely upends when her lifelong best friend, Marie (Doreen Jacobi), introduces her new romantic partner, a photographer named Mark (Clemens Schick). An instant, undeniable spark ignites between Karen and Mark. Despite their crushing guilt and the threat to both relationships, they surrender to a passionate, secret affair that becomes devastatingly complicated when Mark and Marie plan to marry, and Karen discovers she is pregnant.
