Minneapolis cop team Sam Kovac and Nikki Liska feel they must investigate the death of a colleague. Widely suspected of being gay, Andy Fallon has been written off as a suicide, but when the two begin to poke into old evidence, they find that the case is more complex than anyone expected, and when another murder occurs, they know they`re on to something. In the process of discovering exactly what that is, they must resuscitate a case that`s 20 years dead--and they also find themselves in deadly danger.
