Lenka is a high-earning manager in the global finance sector. She lives for her work and is on the verge of achieving success in her life: if she manages to close a deal with a Turkish company, she will become the director of the company for the whole of Asia. However, because of her work, she neglects her loved ones—her husband Jiří, a university professor, and her teenage son Patrik, who is currently experiencing his first relationship. A foolish bet with her son that she can skate more than 100 meters on roller skates proves fatal – she wins the bet, but immediately breaks both her wrists.
