Three EastEnders characters will be forced to become fire fighters in the soap next week.

Warning: spoiler alert!

Shirley (Linda Henry), Jean (Gillian Wright) and Bianca (Patsy Palmer) go back to Ian's (Adam Woodyatt) restaurant after hours so Jean can retrieve her handbag.

They gain entrance via the restaurant's back door and light candles.

Shirley decides to open Ian's special bottle of brandy but accidently smashes it near a naked flame.

Viewers can see what happens next on BBC One and RTÉ One on Thursday July 4.
