They were one of the most successful and iconic boybands - but behind-the-scenes, conflict and rivalry, betrayal and tragedy led to their falling apart.
Now, thirty years on, all four remaining members - Ronan Keating, Keith Duffy, Shane Lynch and Michael 'Mikey’ Graham, as well as their estranged manager, Louis Walsh – reveal what really happened, the extraordinary highs of their meteoric rise to fame, and the huge costs that being in a boyband had on each of them.
In the first of three episodes, five working-class lads from Dublin are plucked from obscurity and given the chance of a lifetime.
After a rocky start (remember that Late Late Show episode?), their popularity grows and they’re soon travelling the world in pursuit of fame and fortune.
But behind-the-scenes, bitter rifts threaten to divide the band as personal insecurities are exploited.
Manager Louis Walsh sets about ruthlessly manipulating the press, as a secret about one of the members’ sexuality surfaces, with devastating ramifications.
Miss Austen, 9.05pm, BBC One
Historical drama's what the BBC are probably best at - and here's another potential treat, and ideal Sunday night viewing.
It's based on Gill Hornby's novel and stars Keeley Hawes as Jane Austen's lesser-known sister, Cassandra.
Years after the author's death, Cassandra pays a visit to a young woman who faces losing her home after her father's death.
But her real motive is to find a hidden bundle of private letters which, in the wrong hands, she fears could destroy Jane's reputation.
The series also stars Rose Leslie and Patsy Ferran.
Here’s a psychological crime thriller series (originally screened on Channel 4), starring James Nesbitt, Richard E Grant, Ben Miller, Joely Richardson, Anne-Marie Duff, and Niamh Algar.
When veteran detective Danny Frater turns up at a hospital mortuary for what he thinks is a routine ID check, he gets a devastating shock.
The deceased - a young woman - turns out to be his estranged daughter, Christina. According to the post-mortem report, she's taken her own life.
Although the pathologist, Jackie Sowden, insists that the evidence points overwhelmingly toward suicide, Danny refuses to accept her findings, and he forces Jackie to take him through her examination step-by-step.
