An unknown man is found dead on the banks of the Rhine. He suffered a heart attack. However, he was not alone at the time of his death; someone previously sprayed pepper spray into his face. The investigators Odenthal and Stern notice a mysterious witness: Julia, in her mid-40s. Everything indicates that she saw the man or even specifically met him. The two Ludwigshafen detectives uncover the tragedy in Julia's life, layer by layer. It's about her foster daughter, the young Sina, who recently became the victim of a crime herself, on the World Wide Web, which promises and promises a lot and strikes mercilessly when a young teenager entrusts him with everything she owns - her trust, her innocence, their hope. At some point, Odenthal and Stern are sure: Julia is looking for the person responsible for Sina's death. And she doesn't shy away from continuing on and leaving a trail of death behind her until she finds him. She is the avatar.
