London's Burning

New recruits Geoff Pearce and Billy Ray settle in at Blackwall.

Hallam and the Fire Investigation team look into a possible arson attack on a run-down estate.

Billy has to step in when tensions run high between Pearce and Bayleaf; Sicknote is still attracting unwanted attention from Cynthia; the crew is called to a dangerous situation in a cold store.

While romance blooms with Diana and Nick, Colin is still stuck between his mother and Zoe; disaster strikes at the warehouse used as a refuge by vagrants; it's Sicknote's big night at the theater.

Sicknote is in the doghouse; Recall receives some news; Pearce's true character is revealed; Blue Watch must save a mother and child after a car transporter ploughs into some scaffolding.

Called out to rescue a rigger off an old lady's roof, Sally and the boys play some tricks on each other; Pearce's wife Patti has ambitions to climb the social ladder, but Sandra's horrified to hear they will be neighbors.

George is not happy to learn he didn't win a fair fight; Patti relishes getting involved in Sicknote and Jean's problems; when a car chase collides with a parked gas tanker, an inferno traps innocent bystanders.

A student party goes up in flames.

Bayleaf questions his chances in court; Maggie brings a surprising guest to the party.

Hallam must make an important decision; a derelict building holds unforeseen dangers.
