Casualty certainly means business with the unveiling of an explosive summer trailer.

The new footage reveals a shock accident that occurs on Zoe and Max's wedding day, Chucky Venn's arrival as new nurse Jacob Masters and his flirtation with Connie. Watch below:

The trailer also features the return of Chelsee Healey as Honey Wright, more family trouble for Charlie, plus the latest stunts that will bring patients into the emergency department.

Casualty scriptwriter Mark Catley recently defended himself after penning one of the show's most divisive episodes in history.

The long-running medical drama sparked outrage on Twitter at the weekend by airing a special film noir-style edition titled 'Holby Sin City', which focussed on a complex murder case.
