What is The Cage about?

The series follows Leanne, a charismatic cashier at an inner-city casino in Liverpool, who starts skimming cash from the safe when she’s threatened with losing her home. When she discovers that her boss Matty is also taking money from the safe, “their lives are set on a collision course; with each other, the local gangster they’re stealing from, and the police”.

The synopsis continues: “As Leanne’s loyalties are pulled in different directions, Matty battles with his inner demons meaning the pair will have to play every hand perfectly.”

Speaking about the show during an appearance on ITV’s This Morning, Sheridan said of the main duo: “They’re not great at stealing. My character Leanne is much more organised but Matty is letting the side down, he’s not very reliable.
