Hollyoaks High is rocked by a massive explosion and lives are left hanging in the balance following a deadly  gas leak caused by Mac.

Earlier on a furious Mac is seething with jealousy over Neeta and Hunter’s affair and storms into the school where he has an almighty showdown with his girlfriend as he drags her into the school’s boiler room.

When Neeta shows him a drawing of her and Hunter together, jealous Mac sees red and in a fit of anger he hits the gas boiler with a bar, before setting fire to the picture.

Disaster strikes when Mac’s actions set off an almighty explosion just as the school prize giving ceremony gets underway!

As the building turns into a blazing inferno, staff, pupils and parents are left running for their lives but who will get away and who will be trapped in the fire and the rapidly crumbling building?
