As a freak storm rocks Holby, a family’s argument reaches boiling point, while an ED favourite ends up fighting for their life.
After an argument with Louise, Big Mac is feeling isolated from the gang and fed up. But when his long-lost friend Snapper is brought into the ED after being injured in the storm, Big Mac finds a cause he can get behind and tries to persuade his grumpy friend to have urgent surgery.
Elsewhere Jeff and Tamzin bring in the Eldon family – mum Maria, dad Gray and daughters Maddy and Siana. As Gray is treated for a fractured skull, Tom, Jeff and Tamzin are left to piece together the puzzle of what really happened behind closed doors. Was it an accident, a case of a self-defence or something more complicated?
