Number One Fan - Season 1

Lucy Logan is the hottest TV star in the country. With a hit morning show, huge following on social media, and a gorgeous family, her life is perfect. Enter Donna.

Walking through a car park Lucy's handbag is swiped by a mugger and Donna intervenes to save the day. Donna is Lucy's biggest fan and Lucy invites her to visit her on set of her show in gratitude.

Lucy thinks that's the end of it, but wherever Lucy goes Donna's there too. In her studio audiences, at launch events, when she's shopping, on the school run, outside her house. Lucy can't escape her, as what starts off as obsessive fan turns sinister.

Rocked by Donna's claims, Lucy's head is spinning. Helped by her manager Mel, Lucy attempts to regain control ahead of The British Entertainment Awards ceremony, where she's a shoo-in for victory. But Donna won't answer her calls.

Panicked, Lucy's in damage control, hoping to get hold of exiled presenter Stewart Jones. But he's resentful of Lucy's success compared to his fall from grace due to the death of Ben Hughes.

As Lucy's paranoia grows, she baits Donna, saying she'll admit the truth if she leaves her alone. Donna agrees but on one condition – she does it at the awards ceremony with the whole world watching. But can Lucy go through with it?

With Donna watching on, Lucy doesn't bite. But this only infuriates Donna further. She's intent on destroying all that Lucy holds dear as Donna threatens to release footage that will ruin Lucy's life.

But a determined Lucy fights back to dig up dirt on Donna with Mel's help. Her plan backfires when Donna admits the truth.

Meanwhile, Jacob's affection towards Vince grows. In an attempt to win favour, he takes part in a protest at a fuel depot, chaining himself to a fence. And when Lucy finds out - it's Donna standing next an oblivious Jacob. As Lucy struggles to keep it together, she tells Shawn and Jacob the truth.

Then, when Donna releases the footage to rival presenter Jane Shelley, Lucy's career is seemingly over. And as Lucy confronts Donna, Donna is left with blood on her hands…

Lucy goes missing, presumed dead by suicide, but Donna is hatching a plan to make the real culprit take the fall...
