Marlene (Stefanie von Poser) is shot by a crossbow during the legendary "blood procession" with over 3.000 horses. She survives, but has to be put in an artificial coma.
Her son Oliver (Marlon Boess) has only recently returned to Lake Constance: the family blamed him for the death of his godmother, who died three years ago together with a precious racehorse. Shortly before being shot, Marlene thought she saw the same horse, alive, at the procession.
Detectives Micha Oberländer and Hannah Zeiler get to the bottom of the mystery around this enigmatic animal and the relation between power and greed in the world of horses.
