Severe weather conditions place the casualty department under even more pressure than usual. Dr Julian and his sidekick Sister Benita treat a pensioner with a broken ankle and a former miner with a chronic lung condition. Meanwhile, Dr Jane treats four-year-old Teddy after a sledging accident.

Patient numbers are through the roof, and the team are facing one of the busiest days in the A&E's history. Keeping the team going through this incredibly pressured shift is the self-named Emergency Clown Sister Jane, who takes the younger nurses under her wing and boosts morale with a dose of laughter.
