Channel 5's new drama, The Night Caller, features a star-studded cast including Robert Glenister, Sean Pertwee, Suzanne Packer and Stephen Walters.
The series delves into the life of taxi driver Tony, who has an "unhealthy obsession" with late-night radio talk-show host Lawrence.
The Night Caller is a unique exploration of loneliness, described by its cast as a "very real and different," series that deviates from the typical cop drama, offering numerous twists and turns.
Tony, a man in his 50s, was once a respected teacher but after losing his job, his self-esteem took a hit, his marriage fell apart and he became increasingly isolated.
