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. Andi had been receiving homophobic hate mail for several years, and the letters grew uglier after the couple's baby was born.

Bern homicide Detective Giuliana Linder is assigned to investigate what happened to Andi. As she pieces together the details of Andi and Nisha's lives, her assistant Renzo Donatelli looks into Andi's job advising young men drafted into Switzerland's civilian service. Working closely together, Giuliana and Renzo are again 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--perhaps enough to get rid of her.
