As The Doctor is about to be hypnotised he gets out his sonic screwdriver and reverses the effects. The head and sevral slitheen get hypnotised for a few minutes giving time for Harry and the doctor to escape. Meanwhile Mr. Roberts jumps in just in time to save Kaylie from a slitheen and Zac, Kaylie, Harry and the doctor run outside.

Georgia accidentaly calls a slitheen Racsonfess when he isn't Racsonfess. Georgia then says it's because the slitheen all look the same. The slitheen begin to argue about who looks the nicest and Georgia manages to snap Richard out of his hypnotism stage. Richard and Georgia escape and soon meet up with Zac, Kaylie and Harry. The doctor meanwhile has gone back into the school to find Conner who was surrounded by Mrs. Harrison and Mr. Ashmer. The doctor finds Conner with help from Mr. Roberts and they find him knocked out. Conner wakes up while the doctor is talking to the two teachers and throws his schoolbag at them. They are temporarily confused and the three goodies escape.

The crew, now consisting of the doctor, Conner, Georgia, Zac, Kaylie, Harry, Richard and Mr. Roberts, decide to contact someone who can help them. The slitheen however are cutting off comunications. Georgia's parents are found by slitheen, as is Zac's mum. When the doctor phones Colonel Mace of UNIT and plays a message from Commander Marr to UNIT meaning Marr is still alive, the slitheen cut the phone lines meaning Mace is cut off before saying something important.

Georgia decides to take the crew to Brisn her old boyfriend where they make plans. Zac, Kaylie, Conner and Harry go off to destroy the machine which is now controlling the children. The children are now marching to war and Georgia's parents are waking up in their house nearby the school! Richard, Brian and Georgia, meanwhile, have managed to transmit a message from a television studio in South London, telling the city to clear because the children are marching around shooting everyone with the guns the slitheen have given them. At the end of the transmission a slitheen is seen attacking Georgia and Richard!

Zac, Harry, Conner and Kaylie, meanwhile use the sonic screwdriver to free Catherine and Kaylie of hypnotism. Zac runs into the school when Bradley and his hypnotised gang with guns appear. They are about to kill Beth, Catherine, Conner, Kaylie and Harry when Zac smashes the hynosis machine in the head's office. All the children run off dropping their guns and running home. Bert then appears and Kaylie argues with Conner about Bert being a slitheen when a slitheen kills Bert, the arguement is settled!

Brian manages to revive Georgia in the television studios but Richard has been killed. The doctor and Mr. Roberts, still in Brian's house are surrounded by slitheen and then Mr. Roberts reveals that he is a slitheen in the only slimline skinsuit that theseslitheen have. Mr. Roberts has been a slitheen from the very start and everyone has trusted him. The doctor kills Tron slitheen(Mr. Roberts) with vinegar and runs off to meet Brian and Georgia, who is crying.

The entire crew get to Richard's old fish and chip shop. The doctor tries to lure the lsitheen here and attemps to spill vinegar over the floor. The vinegar is in a large barrel. Then the slitheen turn up hypnotising the doctor, Conner, Georgia, Harry, Brian to go and fly the TARDIS into a black hole. Before the Head can hypnotise Zac, Kaylie stands up and shouts at the slitheen. Zac realises there is a tap on the barrel and turns it fully so a huge spurt of vinegar shoots out of the barrel killing all the slitheen.

It is at Richard's funeral where Georgia and Brian have a quiet and sad conversation. They decide that although they love each other they are not readdy to give up the TARDIS or Earth. Georgia's parents are sobbing in the backround and Kaylie and Harry say goodbye to Zac as they walk home. Brian refuses to go in the TARDIS so Georgia asks Zac who saved the lives of the entire crew.

The story of Zac traveling as a TARDIS companion continues in Spirits of the Past...
