The ward is abuzz with the news a female boxer is on the ward, suffering from concussion due to a knockout punch in training. Charlie and her trainer Jimmy are itching to get out of All Saints and back in the ring — she is not too keen on hanging around for a CT scan — even though Luke fears she may have a cerebral bleed. But Steph suspects there may be other factors behind Charlie's symptoms, and a urine test confirms she is pregnant. Terrified a pregnancy will mean the end of her boxing career, Charlie demands an abortion. There's only one hitch, Luke refuses to write a referral, claiming there is no medical reason for a termination.

While nursing Charlie, Steph realises the young boxers's views on pregnancy are not as clear cut as she initially made out — especially when Steph points out motherhood need not mean the end of her promising career.

It is a race against time which Ben appears to be losing when the patient suffers a cardiac arrest. Ben knows the only way he can save the patient is by relying on Jason's assistance — but is it a risk he is prepared to take?
