An incident from the past returns to haunt the wife of an ambitious politician which could falter his career. The series is very well acted as each episode exposes a new truth which leaves you wondering who are the good people and who are the bad. It all begins with a tragic incident involving their son and the plot goes on to twist and turn and draws you in. The side stories are interesting and the cast all do an excellent job as your initial opinion of some of the characters over time changes as their true nature is exposed. It is well written and I enjoyed the pace and the main character played by Kim Hyun Joo shows great strength as her life unravels.
