• Mrs. S is Sarah and Felix’s adoptive mother who brought them to North America in the late '90s. A mother hen figure whose compassion is matched only by the hard love she dishes out, S has also been the on-again off-again caretaker of Sarah’s daughter Kira — keeping her safe from the wild ways and questionable acquaintances of her rebellious mother. But S isn’t as scrupulous as she may seem; she remains connected to an underground organization of activists who don’t shy away from violence if necessary. An unlikely reunion with her mother Kendall reawakens S’ protective instincts, and her fierce desire to take matters into her own hands.
