When advertising professional Conrad is stranded in the convent on a business trip, Charlotte feels vindicated in her decision to choose life in the convent. But the convent is in the red and has been making losses for too long, which is why the unexpected guest comes at just the right time for Abbess Katharina and Sister Hedi. With his experience and skills, he could make the convent profitable again and save it from being sold. Although Charlotte has another plan to save the convent, she reluctantly agrees to work with Conrad.
