After all departments have found themselves under huge amounts of pressure, Holby City finally hits a code red, with the hospital full to capacity, patients on trolleys in corridors and a shortage of staff.
And when the shutdown leads to ambulances queuing outside the hospital, Dr Alicia Munroe (played by Chelsea Halfpenny) is furious that patients are being put in danger.
Especially when one of her own patients is put in a desperate situation, and another patient’s family stress leads to Alicia’s assault.
With new Clinical Lead Ethan Hardy having to play musical beds, poor Alicia, along with the rest of the department, are furious that the situation is so bad.
