A new boxset begins in tomorrow’s episode of BBC drama Casualty and this time, the paramedics are in the spotlight.

Supply and Demand will delve into the harrowing realities of a drug crisis. An interruption to the illegal drug supply chain puts pressure on the entire ED, who are also under strain from clinical drugs shortages.

As addicts scour the streets, hospital medics will struggle to fill prescriptions.

There’s a lot going on in the opening instalment so, ahead of the broadcast, here’s all the spoilers you need to know.

The paramedic team falls apart

Following Indie Jankowski’s (Naomi Wakszlak) ambulance crash and the confession about the burglary, the dynamic between her and Jan Jennings (Di Botcher) remains tense. When we re-join the characters tomorrow, it’s been three months since these events, but Jan is struggling to move past them.

As a result of Iain Dean (Michael Stevenson) believing that Indie deserves a second chance, he starts to view the team differently, and realises the group he’s worked hard to nurture is starting to fall apart.

Iain’s offer

When Iain is offered a secondment at Hart, he is certainly tempted. We’ve previously seen the character leave his role at Holby ED to work at HEMs, but the Hazardous Area Response Team would see Iain dip into another side of being a paramedic.

Intrigued by the dangerous events he would find himself in, Iain starts to wonder what his future looks like, given cracks are beginning to form between him and the other paramedics.

Flynn’s new challenge

Flynn Byron (Olly Rix), the ED’s Clinical Lead, learns the pharmacy has restricted liquid salbutamol. When an end-of-life patient desperately needs it, he confronts pharmacist Sunny. She explains they are in a difficult position and need to stockpile the supply, and Flynn promises to speak to the board about the problem.

Flynn’s ever growing list of tasks gets slightly longer moments later, as his children arrive at the ED. He needs to look after them and work at the same time – can he manage it?

Rash’s romance

Oh my god, standby. Rash Masum (Neet Mohan) might finally be getting a romance storyline! When he heads up to the pharmacy to get his antidepressants prescription, Sunny notes that his dosage has decreased.

They get talking, and Rash smiles because he’s been noticed by her.

Fingers crossed!

Stevie’s news

Following her cancer journey in the last mini-series, Stevie (Elinor Lawless) informs Flynn that she’s just finished her chemo, and will be returning to work in two weeks.

Ngozi’s battle

Last week, Ngozi Okoye (Adesuwa Oni) told Nicole Piper (Sammy T Dobson) about her alcoholism. In a shocking move though, Nicole ended their relationship moments after.

In tomorrow’s episode, things remain tense between Nicole and Ngozi, and they end up making a mistake while working together.

Dylan (William Beck) tries to convince Ngozi to go to an AA meeting, but she doesn’t think she has a drinking problem, and tells Dylan he can breathalyse her before every shift to prove it.

BBC One’s Casualty is currently in the middle of being put out to competitive tendering.

The process will decide which producer makes the show, though the BBC will retain all the rights for the programme.
