She thought she knew her husband, but he's been keeping a secret ... about her.

Scottish politician Susie Wallace is under pressure. She risks censure from her Party for her passionate and outspoken views on arts funding. A charity she's involved with runs into difficulties. And a certain journalist seems to have it in for her.

Susie stumbles across some information that rocks her world but not, apparently, her husband's - Archie has been in on this particular secret for thirty years. Now Susie wonders if she can trust him at all. Soon, unemployed son Jonathan and successful daughter Mannie begin to feel the fallout too, fracturing the family and leaving Susie increasingly isolated.

Troubled by mounting pressure from her family, her Party and the Press, Susie goes into hiding. The Party needs her back for a crucial vote, but more importantly, Archie knows he needs to find his wife quickly if they are to rebuild their relationship and reunite the family.
