[1][2] Focusing on the activities of the detectives of the local Garda Síochána station and townsfolk, three series of the programme were broadcast, concluding just over five years from the date of its debut, on January 8, 2020.

The series featured an ensemble cast of recognisable Irish talent, including Richard Flood, Conor Mullen, Jane McGrath and Cathy Belton, and was filmed on location in Dublin, including studios based at the old John Player Factory, as well as Howth and Dún Laoghaire.

Upon commission, the channel revealed that forty weeks worth of episodes had been slated, to air right through until December of that year, with a mid-series break.

[6] Despite a brief slump in ratings, it grew to become TV3's most popular show, with repeats of the first series airing during the summer hiatus due to viewer demand.

TV3 director of programming Bill Malone also stated that the viewing figures for these episodes would ultimately decide on the series' long-term future.

[9] It was also reported that despite it being publicised as a hiatus, production on the series had actually ceased, with props and sets being sold off at public auction.

Darren Kiely is found badly beaten on Red Rock Pier; he later dies from his injuries.

This brings absent mother Bridget Kiely back into the lives of her children Katie and Keith, and husband Vincent.

To make the situation more complicated Michael's brother David is in a relationship with Katie, something he keeps secret from his solicitor sister Claire and overbearing mother Patricia.

A bitter and angry Michael revealed this to Katie who quickly ended the relationship and reported David's involvement with Darren's death to the gardaí.

David is eventually cleared of all charges due to lack of evidence; he was just about to move on with his life when Katie tells him that she is pregnant and he's the father.

Not long into investigating what happened the night Darren Kiely died she is scanning CCTV footage for the suspect when she sees Sergeant Brian McGonigle in a car kissing a teenage girl in a school uniform.

That's when McKay reveals that Brian has already spoken to him, telling him that Sharon has been harassing him ever since she came on to him and he turned her down and that she'll accuse him of having an affair with an underage girl.

The next day Rachel still hasn't returned, she becomes suicidal and starts taking sleeping pills mixed with vodka.

As she is being questioned Brian arrives at the station; he pleads his case to McKay who eventually punches him and sends him to the cells.

He owns several houses in Red Rock and is constantly chasing tenants for rent, going so far as selling debt to nefarious loan sharks.

While asking for the driver's licence and registration Adrijan was suddenly run down by a mystery car in the mid season finale.

Two months later it is revealed that Adrijan survived but he may have long term damage resulting in headaches and mood swings.

Her husband Tommy is seeing another woman as he feels it is a loveless marriage that they are just maintaining for the sake of their sons, Conor (a struggling university student) and Stephen, a footballing prodigy.

One of the jobs Beady gives Paudge is to inform McKay of the drug dealing operation of his competition, Laser Byrne.

Meanwhile, Webb is having a tough time being McKay's informant: Laser knows what he's up to and has his house petrol bombed - Davey's younger sister Chloe is scarred for life.

Davey Webb pays a visit to Claire, now a grieving widow, she deciphers from his behaviour that he was the one who killed McKay and he goes on the run only to be eventually caught by Sean and Adrijan.

Meanwhile, a guilt ridden Paudge eventually lets it slip to Sharon that he was giving Beady garda information and McKay found out.

Adrijan can't stand this and decides it is time to leave Red Rock and return home to Croatia.

Brian hasn't been seen since his charge of sexual relations with a minor but arrives back in Red Rock with a plan.

To reunite with his family, restart his relationship with Rachel and convince her to retract her statement, blackmail Angela into not testifying at his trial and besmirch Sharon's name.

Rachel and Liam decide to keep quiet as the evidence piles up against Conor and Angela's career and reputation gets more and more damaged as she fights to clear her son's name.
