The attractive young Franka runs the traditional porcelain manufactory Rhomberg with her father. In contrast to her fun-loving sister Joe, the sensible Franka has no time for men. That changes when she meets the sensitive, good-looking Luca - who unfortunately has just married her "best enemy" Nathalie. Franka suddenly has to fight against unfamiliar feelings. Joe falls seriously in love too, but is the easy-going bartender Marco the right one for her? The lives of the two sisters are turned upside down.
