Episodes
In 1942 code-breaker Claire Hopkins is the victim of an unsolved murder. Fourteen years later, her former colleagues Millie and Jean read of two murders in San Francisco identical to Claire's and the pair travel to the city to meet war-time counterparts Iris Bearden and Hailey Yarner. Iris's son Dennis, a civil rights activist, is part of a group opposing property developers bull-dozing their district, Fillmore, for gentrification. After a third murder the women find a possible clue to the killer in a letter to the local paper.
Subsequent deaths make it clear: San Francisco is in the grip of a killer with a dark and complex agenda now menacing Iris' own neighborhood. The four unlikely allies struggle to work together - and in the process, not only expose a twisted operation, but also forge powerful and lasting bonds.
Our four women delve into the mysterious death of Iris' suburban friend, uncovering a complex cluster of marriages built on lies and deception. In her quest to forge a new life, Millie must confront a long-lost cousin, who may hold the key to a future in San Francisco.
After a seemingly innocent man is charged with murder, the women become enmeshed in a tangled suburban tragedy, racing to find both the true killer and the methods before the scent goes cold. Jean meanwhile grapples with how -and where - to build a new life for herself.
A bloodied and battered stranger collapses on Millie and Jean's doorstep, dragging them into a mysterious criminal underworld. In a race against time, the four women must unravel the patterns behind a series of attacks in order to avoid becoming the next victims.
Two female British code breakers team with American cryptographers to solve a series of murders in San Francisco.
