Pick of the day... The Plot To Kill Holly Willoughby, Channel 5, 9pm

Fans of This Morning were sent into a frenzy one Thursday when long-time host Holly Willoughby didn’t turn up for work. What we didn’t know is that 12 hours earlier, police had bashed down the door of a suspect who had plotted to kidnap, sexually assault and murder her - spinning Holly’s life on its head in that moment. This documentary examines the details of this crime, which tells of the horrific plan by 37-year-old Essex security guard Gavin Plumb.

In July last year, Plumb was convicted soliciting the kidnap, rape and murder of Holly, having spent nearly a decade developing a twisted fixation on her. He amassed tens of thousands of images, tracked her movements, researched her home and security arrangements and had recruited other like-minded men to help turn his sick sexual fantasies into reality. Their plan was to invade the star’s London home - subdue her husband with chloroform and use the couple’s young children as leverage.

They intended to kidnap Holly, drive her to a remote location where she would be viciously sexually assaulted and ultimately, murdered. When Holly learned of the plan, just hours before she was due to go on air, her life was changed forever. With little choice but to put her glittering career on hold, she withdrew from public life whilst the police built their case against Plumb. Would his plan ever come to pass or was it nothing more than a sick fantasy? Holly refused to participate in this documentary, but there is commentary from journalists and experts in criminal psychology, as it rakes over the details of a crime that shocked the nation.

The Best of the Rest... Taskmaster, Channel 4, 9pm

The most absurd and brilliant game show returns, with Greg Davies as fickle overlord and Little Alex Horne as his subservient sidekick.

Each are hoping to win valuable points, eternal glory, and favourable treatment from the Taskmaster, but they will soon learn that nothing makes sense, everything is utterly pointless and favour is hard to win. Four of them will eventually exit the show broken and beaten, while one will exit broken, beaten and with a rubbish prize. In the first prize task, a golf club and a map remind everyone of school - in a good way. They must demonstrate their skills in tasks involving vinegar, raisins and peas. Find out also what makes everyone describe Alex as ‘cool’. It’s never been said before…

The Four Seasons, Netflix

With a starry Hollywood cast, this is a fresh take on an age-old saga - a break up. Tina Fey, Steve Carell, Colman Domingo, Will Forte, Kerri Kenney-Silver and Marco Calvani star as three married couples who have been friends for 30 years. Every season, they all go away together for the weekend, but this glorious tradition is about to be smashed to pieces when one of the couples divorces.

Tina, who wrote the show alongside 30 Rock writer producers Lang Fisher and Tracey Wigfield, said: “I hope audiences feel like they are inside a big sweater with us, and also having a dinner party with us, and I hope that any of the joy and warmth that we all feel for each other all transfers to them.” The show, which has been compared to The White Lotus (minus the deaths), has a lot to unpack as these couples navigate their weekend getaways with a whole new dynamic.
