In the first episode of season 1, we are introduced to Gemma Foster, a middle-aged woman who appears to have it all- a successful career as a doctor, a loving husband, Simon (Bertie Carvel), and a son, Tom (Tom Taylor). However, all is not as it seems, and as the episode unfolds, we realize that her seemingly perfect life is on the brink of falling apart.

The episode starts with Gemma in her surgery, seeing her patients. She's professional, respected, and well-liked by her colleagues and patients. After work, she goes home, and we see a glimpse of her domestic life with Simon and Tom. They seem like a happy family, but there is a sense of tension brewing underneath the surface.

As the evening progresses, Gemma prepares dinner while Simon is out. Her world is turned upside down when she discovers a blonde hair on Simon's scarf. We later learn that Simon had told her that he was at a work function, but the blonde hair seems to suggest otherwise. This discovery sets off a chain of events that ultimately puts Gemma's marriage, career, and sanity in jeopardy.

The drama intensifies when Gemma confronts Simon about the blonde hair, but he insists that it was from a colleague. However, she does not believe him and becomes increasingly obsessive about uncovering the truth. She starts to investigate Simon's activities and turns to social media as a tool to get closer to him. Her actions spiral out of control as she becomes consumed by her suspicions.

The episode provides us with a glimpse of Gemma's character- she is strong-willed, resourceful, and tenacious. She is determined to safeguard her family and will do whatever it takes to protect them. However, her relentless pursuit of the truth ultimately puts her in danger.

In summary, the first episode of Doctor Foster sets the tone for the rest of the series. It is a gripping, intense drama that explores the complex themes of marriage, infidelity, and betrayal. The performances by the cast are outstanding, and the writing is clever, subtle, and nuanced. If you're a fan of the psychological thriller genre, then this show will definitely not disappoint.
