Paul Abbott's multi award-winning Shameless returns for a fourth series! Frank (David Threlfall) is sent into a spin when mum Monica (Annabelle Apsion) turns up, claiming to be back for good. Surely the house is not big enough for her and Sheila (Maggie O'Neill)?

Lip (Jody Latham) is juggling with parenting, and Ian (Gerard Kearns) is looking for love. Carl (Elliott Tittensor) is busy on a secret crime spree, while Debbie (Rebecca Ryan) decides to interview potential boyfriends. Carol (Marjorie Yates) is still having trouble keeping her legs and mouth shut, while Kash (Chris Bisson) is happy screwing the council. And what is the connection between Kev, Veronica, Marty, Sue and a Romanian baby?

Meanwhile the Maguires have moved in next door. After a stint in prison, Jamie Maguire (Aaron McCusker) returns and sparks fly with barmaid Karen (Rebecca Atkinson). Then there are his brothers; not-so bright Shane (Nicky Evans) and Micky Maguire (Claran Griffiths), a wannabe hard man struggling with his own secrets.

Life as normal on the Chatsworth estate.
