Andrew Garfield plays Detective Jeb Pyre

Who is Detective Jeb Pyre? Detective Jeb Pyre is an elder in The Church of Jesus Christ of Latter-day Saints who heads up the investigation into the murder of Brenda and her daughter Erica. His faith is rocked following the harrowing ordeal.

"He's very understated, a solid centre of the story that is the audience's eyes," Garfield told Variety. "Not flashy, a very solid dude and internal. I wanted to play with that – be as internal as possible – and less expressive than I've been in recent projects."

What else has Andrew Garfield been in? You'll recognise Andrew Garfield from the Spider-Man franchise, The Eyes of Tammy Faye, Tick, Tick... Boom, Under the Silver Lake, Hacksaw Ridge, The Social Network and Never Let Me Go.

Daisy Edgar-Jones plays Brenda Lafferty

Who is Brenda Lafferty? Brenda Lafferty (24) was studying broadcast journalism at university and she also enjoyed performing arts. She was beaten and stabbed to death by her husband's brothers, Ron and Dan Lafferty, in her home. Her 15-month-old daughter Erica was also killed.

Brenda encouraged Ron's wife Dianna to walk away from their marriage when he announced that he wanted to take a second wife, a practice that Ron and other hardline Mormons consider integral to the faith, despite the church turning its back on ''plural marriage'' in 1890. Men who engage in multiple marriages have one lawful wife and several spiritual wives to circumnavigate bigamy.

What else has Daisy Edgar Jones been in? Daisy Edgar Jones' CV includes Normal People, Fresh, War of the Worlds and Where the Crawdads Sing, while she will this year star in Twisters.

Sam Worthington plays Ron Lafferty

Who was Ron Lafferty? Ron Lafferty was the eldest of the Lafferty sons and was responsible for Brenda's murder.

According to reports, Ron's family had a history of violence – his father was an authoritarian presence – and Ron was described as having a temper. He was excommunicated from the church for his extreme views, which prompted him to establish his own sect in 1984 called the School of the Prophets, which his brothers joined. It was also reported that he was dealing with financial troubles at the time of Brenda's murder.

Richard Stowe and Chloe Low, who were both part of the church, also gave support to Dianna after she left Ron. Following Brenda and Erica's murders, Ron and Dan travelled to the Low house, where they planned to kill Chloe, but she wasn't there. They then drove to Stowe's house, where they planned to do the same, but they missed the turning and did not return.

Ron didn't express any remorse for the murders.
