Both set and filmed in Liverpool and written by policeman-turned-screenwriter Tony schumacher, and has "a beautiful heart" within the quick moving drama.

The series sees Sheridan portray Leanne, a single mum working as a casino cashier. She is also a carer for her Nanna who suffers with dementia, in the aftermath of her own mum's death.

Michael Socha is Matty, Leanne's co-worker at the casino. Matty has problems with addiction, and is staring down the barrel of a sinister outcome if he can't get hold of some cash to pay off the dangerous loan sharks he owes money to.

With both Leanne and Matty working in a place that's built on money, they find themselves within easy reach of the vast amounts they need. The titular 'cage' is "the place in the casino where you cash up, collect your dough and the money is counted," Michael tells the BBC.

When the pair find out they're both out to rob the casino, their lives become tangled in a way that goes on to deliver gripping, high-octane TV, but also gives a brilliant dose of what Sheridan Smith is best at - a tale of "love, family and desperation" that might also "make you cry."

Sheridan has spoken about what to expect from her Leanne and Matty, saying, "It's so fast paced that each character and their stories are interwoven with one another."

She adds, "Leanne also has an excellent poker face. When you see her at home with her family, you see those vulnerabilities on display and the anxiety that’s within her."

"But then when she's in the casino, the mask is on and it's all smiles. The whole show is like one giant poker game" - Matty and Leanne might strike up a friendship, but come to find they can't really trust each other.

When it comes to crime dramas, audiences often want to know if they're based on a true story. While the story itself isn't rooted in reality, Michael Socha's Matty is heartbreakingly based on writer and creator Tony Schumacher's brother.

The writer's brother, Phil, battled with alcoholism and sadly died while The Cage was being filmed.

"Our Phil’s typical timing," Schumacher tells The Royal Television Society. He explains, "My brother was an alcoholic, so there are elements of him in Matty. He was in hospital for 12 weeks with a slow deterioration due to liver and kidney failure."

"Some of the stuff I was giving Michael to deal with was what I was dealing with myself at that time."

While the action will grip you, the flawed but relatable characters and their perfectly written back stories are one of the major draws with this series.

The Cage airs on BBC One and BBC iPlayer from April 26.
