Casualty has released its spring trailer, offering a first glimpse at the storylines to come in the weeks and months ahead.

Faith (Kirsty Mitchell)'s cycle of endless partying comes to an abrupt halt when Luka (Tom Mulheron) is targeted by a predator, while Robyn (Amanda Henderson) faces a difficult decision about her surprise pregnancy.

Meanwhile, Matthew (Osi Okerafor)'s burgeoning relationship with Stevie (Elinor Lawless) comes under strain and he's forced to confront trauma from his past when he has to choose between treating two critically-injured patients.

Elsewhere, paramedic Teddy (Milo Clarke) ignores important signs about his own health, Sah (Erin Smethurst) is confronted by an old bully and Iain (Michael Stevenson) goes beyond the call of duty to help a patient.

"It's going to be a rollercoaster ride in Holby hospital this spring," said Loretta Preece, series producer on Casualty.

"There are difficult choices for Robyn and Teddy, harsh consequences for Stevie and Faith and a hard hitting, action packed and very poignant story for Iain.

"It's a season full of adrenaline and betrayal as well as love, friendship and tenderness.

"Rosie Jones has really touched viewers hearts as Paula and in April we will discover whether the courts will allow her to take her baby back. And after all Ethan has been through this series, might he be ready to move on from Fenisha's memory?"
