Sezon 1

Ruth Gilmartin finds out from her mother that they have been living a double life. She is not respectable Sally Gilmartin but in fact Eva Delectorskaya, a spy for the British Secret Service who has been on the run for 30 years.

When a crucial mission collapses in the USA and Eva Delectorskaya finds herself in terrible, fatal jeopardy, she knows she has no option but to run and hide - forever. The final chapter of this epic story of love, duplicity and betrayal is about to end, and who will pay the greatest price remains to be discovered.
