The Cruise (S03E03)

Hairdresser Jacky Shepherd has booked herself and her husband Andy on a cruise to celebrate their silver wedding anniversary but he is not keen and demands that she cancel. With all her hopes dashed, Jacky begins to worry that her husband is having an affair and follows him to the door of a young woman's house. Could she be the reason he has had such a dramatic change of heart? Or is there a far more peculiar reason behind his reluctance to sail the high seas? (Cinemax)
