Hollyoaks spoilers follow.
Hollyoaks has released its latest dramatic trailer, showcasing all of the biggest storylines hitting our screens in the next couple of months.
Fans can look forward to a returning character, a life-or-death drama for a long-standing resident, and a traumatic time for Mercedes as she's accused of a crime she didn't commit.
Here are 11 of the biggest storylines revealed.
1. Diane's mental health issues escalate
Diane has been struggling with Obsessive Compulsive Disorder (OCD) in the fallout from Edward's reign of terror. Although Tony knows Diane isn't her usual self, he remains oblivious to the full extent of her troubles.
In upcoming episodes, Verity is concerned when she discovers that Diane has covered all of the furniture in plastic to prevent germs around the flat. She urges Tony to address his wife's problems.
When Diane welcomes the arrival of her baby, she also devastates Tony by insisting that nobody can hold their child apart from her.
2. Mercedes is accused of kidnap
Cher has spent weeks tormenting Mercedes by cruelly exploiting the grief she feels over the tragic loss of baby Gabriel. Her scheming goes a step further when she orders a fake pregnancy test to fool Mercedes with. When Mercedes uses the test, she's wrongly convinced that she's pregnant and celebrates with Sylver.
Not stopping there, Cher also snatches Tony and Diane's baby and later frames Mercedes, trying to deceive her into thinking that she is responsible.
3. Darren sleeps with Mandy again
Darren is still desperate to reunite with his ex-wife Nancy, but another foolish mistake threatens to ruin his plans once again.
New footage from the trailer shows Darren lay his heart on the line with Nancy, who's sceptical over whether a reunion could ever work after everything they've already been through together.
Another clip shows Darren confess to Luke that he has recently fallen back into bed with Mandy, which is sure to infuriate Nancy if she ever finds out.
4. Disaster strikes for Darren
Grace is planning to relaunch The Loft and marks the fresh start by commissioning a new sign for the business.
Sadly, Grace's plans lead to disaster when the heavy sign falls on top of Darren in the village, leaving him in a critical condition at the hospital. Nancy remains at his bedside, willing him to come back to her. If Darren survives, could this be the turning point that brings Dancy back together?
5. Grace's life spirals out of control
Hollyoaks has confirmed that Grace's sign disaster will kick off "a series of terrible events" for the no-nonsense nightclub boss.
Grace finds her authority under threat when Warren announces that he's the new manager of The Loft. She clashes with new villain Fergus too, but has she lost the upper hand when she ends up in the back of a police car?
6. Donna-Marie returns
Donna-Marie has been messaging Juliet recently and threatened to make an appearance in person when her daughter was ignoring her. She's true to her word when she surprises Juliet at the local patisserie.
Hollyoaks has confirmed that Donna-Marie will be desperate to prove to her children that she has changed when she returns, but whether she can really be trusted remains to be seen.
7. Summer finalises her revenge plans
Summer gets her wish when she starts an affair with Sienna, after weeks of building chemistry between them. Summer's boyfriend Brody remains oblivious to what she's up to and even proposes to her.
Summer also continues to keep her sinister secret as she's still plotting to destroy Brody's life. She privately vows to give him the worst day of his life, on the day that's supposed to be his best.
Brody also looks set to face a devastating discovery as the new trailer appears to show that he'll catch Summer and Sienna in the act.
8. Liberty in danger
The sisterly bond between Liberty and Sienna has endured its fair share of challenges, but their relationship takes a surprising turn when Sienna threatens her sibling. This is sure to make Sienna a top suspect when Liberty later disappears.
Summer – another likely suspect – is also shown with a highly toxic substance as her scheming continues. Is Liberty going to be poisoned?
9. Shaq wants answers over his family
Shaq seemed happy and carefree when he joined the village in March, but there's lots more going on underneath the surface. Viewers are about to learn that Shaq has some big unanswered questions about his past.
Shaq wants to know who his father is and the trailer shows him reflecting on this missing link in his family set-up: "It's just this horrible, constant feeling in the pit of my stomach – who's my dad?"
10. Martine's treatment continues
Martine has been diagnosed with breast cancer and will be having treatment at the hospital over the coming months.
New footage from the trailer sees Martine's father Walter become concerned that her health is deteriorating, so he urges her to speak to the doctors. Grace also worries when Martine is unsteady on her feet at The Loft.
Martine brushes off everyone's concerns but is given food for thought when Celeste reveals how worried she and Toby are about potentially losing her.
11. Cindy makes a big mistake
Ollie is returning to the village following his time in rehab, but not everyone seems pleased to see him back. Cindy makes a devastating mistake when she tries to pay off Ollie to leave again, fearing that Luke isn't in the right frame of mind to deal with him.
Luke is outraged when he finds out what Cindy has done, and his interfering mum Sue reckons he should end things with her for good.
