Cool influencer and true city boy Leon decided to spend his summer at a stud farm. He's initially far from impressed by Immenhof, which since the death of the owner-manager is naively run by the sisters Lou(ise), firstborn Charly and pre-teen Emmie, who know enough about horses, little about business, yet lets them exploit him as free stable hand. Leon cockily rivals with generous neighbor Matz, who constantly helps them out for free, having an eye on Lou. The tycoon owner of the prestigious adjoining stud farm, Jochen Mallinckroth, owns their debts and decides to call them after his latest top-price stallion Caliostro was saved from a sinkhole but too scared to even enter the stables again. While stable-master Viktor seeks a compromise, ambitious trainer Runa encourages the foreclosure plan, in order to get hold of Lou's former Olmpic medal win mount, Holly. Desperate, Lou offers a daring bet, while trying to deny she falls in love with handsome, helpful Leon.
