1941. The Clydebank Blitz robs Nessa Glover of her husband and five children.

Struggling with her new reality she becomes a shipyard welder, and finds herself drawn into trade union activism.

One day she visits Harmony, a commune built on notions of equality and unity, led by the charismatic Fergus Abercrombie.

But not everything is quite as it seems at Harmony. 1980. Keir Connor is a traumatised war correspondent. When his father dies, he is left with a letter – a letter that takes him to Clydebank in search of answers.

His journey leads him on to Harmony, now Laggandarroch, a residential school for disadvantaged children, as he tries to unlock the past.

One thing is sure: Harmony is key.
