Set in Hackney, the series depicts a 22-year-old Jane Tennison as she begins her career as a WPC with the Metropolitan Police Service in 1973. At a time when women were beginning to be gradually integrated into the police force, Tennison has to deal with sexism, as well as difficulties in her home life as her family disapprove of her career choice. Under the guidance of DI Len Bradfield, the naive and inexperienced Tennison assists in investigating the murder of a young runaway, Julie-Ann Collins. Meanwhile, criminal Clifford Bentley is released from prison and, along with other members of his family, is planning a bank heist. Links to Collins's murder threaten to expose the Bentley family's plans.
The series is produced for ITV by Noho Film and Television, and was adapted by Glen Laker from the novel Tennison, written by original series creator Lynda La Plante. Commissioned by ITV in June 2015 under the working title Tennison, the series was set to be penned by LaPlante, who had also written the original Prime Suspect novels, and contributed to episodes of the long-running television series of the same name. The announcement of Martini as Jane Tennison, as well as further casting was announced in July 2016. In early 2016, La Plante pulled out of the project. Vera and Home Fires writer Glen Laker was drafted in to write the series.
Filming
Filming began in July 2016 in London.
Cancellation
In June 2017, ITV confirmed that the series had not been recommissioned, despite high ratings for the first series. The cause is reported to be creative differences between author Lynda LaPlante and ITV.
Broadcast
Prime Suspect 1973 first aired on 2 March 2017 on ITV. Internationally, broadcast under the title Prime Suspect: Tennison, the series premiered in South Africa on 6 April 2017 on ITV Choice. The series premiered in the United States on 25 June 2017 on Masterpiece Mystery on PBS, airing over three 90-minute instalments. In Australia, the series is set to be broadcast on ABC on 21 July 2017, under its original title.
Reception
The series received mixed reviews from critics, achieving a 50% approval rating based on 12 reviews as aggregated on Rotten Tomatoes. Critics praised Stefanie Martini's performance and the period detail, in particular. Upon its broadcast in the United States, the Washington Post recommended it as "one of the best shows you’ll find on TV this summer", while the Los Angeles Times said that "Tennison does not quite measure up to Prime Suspect." In contrast, Salon considered it fortunate that the series was forced into early retirement, and noted that this Tennison prequel failed to focus on Tennison's character development with the same intensity as the "provocative... classic" sequel did with Helen Mirren's character.
