A respected London surgeon's carefully ordered life starts to unravel the moment his son brings a new fiancée home for dinner, and a single glance across the table sets off a fixation neither of them can walk back.
What is Obsession about?
William has built a comfortable existence around his career, his marriage, and the quiet routines that come with both, until his son introduces Anna, the woman he plans to marry. From their first meeting, William finds himself unable to think about anything else, and Anna, despite every reason to keep her distance, doesn't entirely discourage it. What begins as stolen glances at family gatherings escalates into secret meetings, then into a consuming need that neither party seems able or willing to name out loud. The story unfolds across London's polished interiors and quiet backstreets, tracking how quickly self-control gives way once two people decide a boundary is worth crossing. As the affair deepens, the cost to William's marriage, his son's engagement, and his own composure becomes harder to ignore, building toward a reckoning that touches everyone in his orbit rather than just the two people at its center.
Cast & crew
Richard Armitage plays William with a restrained, simmering intensity that carries the show's central obsession, while Charlie Murphy's Anna matches him with a performance that keeps her motives genuinely ambiguous throughout. Indira Varma appears as William's wife, and Rish Shah plays his son, both caught in the fallout of a relationship they don't fully see coming.
Context & significance
Adapted from Josephine Hart's 1991 novel Damage, the 2023 limited series relocates the story's psychological intensity to a contemporary London setting while keeping its focus on obsession as something closer to compulsion than romance. Its short, four-episode structure keeps the tension compressed rather than drawn out over a full season.
