Those of you who got sucked into the tension-filled hugely successful drama Doctor Foster have no doubt been chomping at the bit for the second season. It aired on the BBC late last year but if you missed it, it finally arrives on RTÉ tonight. Starring Suranne Jones in the titular role, it picks up two years after the events of season one, which saw Gemma Foster discover that her husband Simon (Bertie Carvel) was having an affair with a friend's daughter Kate (Jodie Comer). Gemma is doing well when we first meet her and may even have a romance on the horizon but she is soon brought back to the past with the arrival of Simon into her life once more along with new wife Kate and their young daughter. As you might expect, it's not long before trouble is brewing.
