The Dog explodes - who will survive?

This is the second part of tonight's double-bill.

Sophie is shocked to get a call from Sam and turns to see him standing at the door of The Dog holding a can of petrol.

He holds up his lighter and threatens to set the whole place on fire if anybody moves.

But as everyone tries to escape Sam drops his lighter and the whole pub bursts into flames.

Upstairs Steph desperately tries to rouse Jake from his drowsy alcoholic state…

Frankie and Jack are shocked when they return to a scene of horror and devastation; who will survive the fire?
