Immenhof - Das große Versprechen (2022)

When a poison attack is made on the racehorse Cagliostro, Lou flees the Immenhof with the horse. Together they find refuge with Cal, who lives away from civilization with his semi-wild horses. In his new home, Lou makes the horse promise that it will never have to take part in a race again. However, this is by no means the end of the threat to Cagliostro.
