Teenager Sinead O'Connor will give birth in a burnt-out car later this month.
The mouthy shop worker only has her brother Finn (Keith Rice) and Esther Bloom (Jazmine Franks) to support her as she goes into labour in a remote location.
Sinead's ordeal begins when she discovers that Finn was involved in an armed robbery at Price Slice, which has left Callum Kane fighting for his life.
Needing to find her brother, Sinead teams up with Esther and tracks him down at an abandoned petrol station.
Sinead's plans to confront her wayward sibling are then suddenly interrupted as she starts experiencing contractions.
With Sinead needing to get comfortable somewhere, a supportive Esther guides her over to a burnt-out car, before helping to deliver the baby.
The dramatic scenes could bring Sinead and Esther closer together again after they were at the centre of a dark bullying storyline a few months ago.
Stephanie Davis, who plays Sinead, told All About Soap: "Sinead really isn't prepared and Esther's being quite tough. Sinead keeps saying, 'I can't do this - I give up', and Esther gives her a big whack across the face!
"She yells at Esther, 'That's what you've always wanted to do, isn't it?' and she replies, 'Yes it is, now push!' That's when Sinead and Esther begin to bond."
Once Sinead's baby daughter has been delivered, she begins to reconsider her decision to give up the youngster to stepmum Diane.
Davis added: "The baby isn't breathing at first. Finn rings for an ambulance, and poor Sinead is beside herself. She always said that she didn't want this kid, but the minute she's born, Sinead's maternal instincts kick in."
Hollyoaks airs these scenes on Thursday, May 23 at 6.30pm on Channel 4.
Couldn't care less about Callum, I wouldn't miss him if he did die lol. Is Sinead's baby early then? I can't remember when it was that she said she had 10 weeks left?
