Andi Eberhart is riding her bicycle home on an icy winter night when she is killed in a hit-and-run. Her devastated partner Nisha is convinced the death was no accident since Andi had been receiving homophobic hate mail for several years. Nisha, a second-generation immigrant from Sri Lanka, has her own problems; her traditional Tamil father has banished her from the family home and won't acknowledge Nisha and Andi's baby daughter.

Homicide Detective Giuliana Linder is assigned to investigate what happened to Andi. As she pieces together the details of Andi's life with Nisha, her assistant Renzo Donatelli looks into Andi's job counseling young men who've been drafted into Switzerland's civilian service. Things at home are difficult for Renzo, and Giuliana has new family troubles. Once again, they are tempted to become more than just friendly colleagues.

As both detectives dig into Andi's life, one thing becomes clear: Andi's friends and family may have loved her for her honesty, but her outspokenness threatened others. Did one of those people decide to get rid of her?
