A new agency nurse makes quite an impact when they turn up on Keller, as they emerge from the hospital lift trying frantically to resuscitate a patient – it’s former Casualty ED nurse, Ben ‘Lofty’ Chiltern (played by Lee Mead)!

Aware that Lofty left the ED to go travelling following the turmoil of having a nurse die on his watch, Sacha wants to make sure Lofty’s ready to return to work and he assures him he is.

Lofty’s nursing skills are more than a little rusty to say the least, though, and an ill-judged decision sees him come under fire from both Sacha and Dominic! Will Lofty decide that nursing is perhaps not for him? Or is it just what he needs to get his life back on track?
