The series tells of the life of a young woman named Gemma Foster who is a doctor who people trust with time. At some point, Gemma's life appears to be about to explode, believing that her husband is having an affair. Because of that suspicion, Gemma tries to investigate and could cause her family and even some of her patients to live in chaos and destruction daily
It's the small moments that make this a drama worth noticing. Little touches like the almost nonchalant key she drags down the side of her husband's car as she heads out for dinner with her accountant.
Suranne Jones, who plays Gemma, is not only one of the most emotionally uninhibited actresses in television, she is also one of the most brunette. In a world of lies and dyes, her dark locks here connote authenticity.
What could have been an interesting exploration of relationship and infidelity - a subject that never gets old - soon turns into a unconvincing yarn, lined with stereotypes and clunky plot devices with all the believability of a beach read.
It also looked great - the sunny bucolic feel of early scenes giving way to a more sombre palette as he suspicions mounted. I suspect this will get darker as the series progresses.
The script was sparkily written by Olivier Award-winner Mike Bartlett - you could tell he was a playwright from the way he crowbarred in 300-year-old William Congreve quotes - but there were also some stagy narrative contrivances.
