Alys is a Welsh-language television drama series, created by BAFTA Award-winning scriptwriter Siwan Jones and produced by Apollo and Boom Cymru.

[2][3] Supporting cast include William Thomas, Aneirin Hughes, Gillian Elisa, Shelley Rees, and Kate Jarman.

The story revolves around a young woman who flees Cardiff, with her 10-year-old son, trying to escape her troubled past, while her dark secrets eventually begin to surface.

Alys was created and written by Siwan Jones, whose work as a writer earned her a BAFTA Cymru Award and a Rose d'Or for her critically acclaimed television series Tair Chwaer and Con Passionate.

Behind them was a dark tunnel which led into the heart of a building; while they were walking, some children followed along and as she watched on, this triggered the image for the series with became Alys.

Jones' idea which started there was to create two worlds; one of working-class people such as the shop owners in a small town; and the others who were unemployed and struggled to make ends meet, such as Sara Lloyd-Gregory's character, 'Alys'.

Gregory admitted that, to her knowledge, she did not know that the leading role was written for her, which was a good thing, as she still had to audition and would have probably felt more pressure.

[9] William Thomas, was chosen to play the part of Wiliam,[10] the alcoholic ex-minister, and Aneirin Hughes received the role of Toms, both of whom Gregory had appeared alongside on Con Passionate.

23-year-old Rhuddlan-born actress Catrin Mai Hue was chosen for the role of Ceri, an 18-year-old woman with a bleak outlook on life.

[11] Ifan Huw Dafydd, who also appeared in Jones' Con Passionate, was cast as in the series as Ron, an overweight, financial consultant who hides a disturbing, dark secret.

[15] Alys, a young mother arrives at a small town in West Wales, having escaped her troubled past in Cardiff, involving the death of her brother from a drug overdose and her boyfriend who died in a car accident.

Alys will do all that she can to make ends meet; including robbery, blackmail and prostitution, with Toms becoming a regular client.

Alys comes to realise that she has more to worry about than what the town thinks of her; she and Wiliam track down the taxi driver, Terry, who raped Ceri and they are determined to make him suffer.

Not only does she have problems with Terry, it is later revealed that Heulwen is her aunt, her mother's sister, and when Ron's house is robbed, Alys becomes in possession of his laptop and discovers the pictures.

Twelve months pass; the whereabouts of Wiliam are still unknown until he suddenly arrives and moves in with Alys.

Alys is determined to uncover the truth behind Ceri's murder and is aware that Terry, the taxi driver is behind it and is going to make him pay.

Meanwhile, Heulwen, unable to pay the mortgage on her home, following Toms' bankruptcy and his breakdown, is forced to live in a caravan in her back garden, while receiving frequent visits from Alys, whom she has revealed to be her aunt.

[20] However, this operation ceased and the final five episodes of series 2 could only be screened in standard-definition on the original channel as S4C Clirlun closed on 1 December 2012.

Both series were made available to watch online in the UK after the television broadcast, on VOD service S4C Clic, for 35 days only.

[22] on 29 April 2019, series 1 was made available for streaming on the Clic service (UK only) - for the first time since the original screening.

Although it may not have officially been cancelled, it is currently unknown if the series will return, despite the fact that viewers were left with an unresolved cliffhanger.

In a 2013 interview with the Wales Arts Review, Sara Lloyd-Gregory commented: "At the moment, there isn’t talk of another series of Alys.
