Judy and Mouse dig in the rubble with their bare hands, but they only turn up Irene's dead body . They shout for help and hear Bea's voice on the other side of the cave-in: Bea tells them that Doreen and Lizzie are still alive. Meanwhile, Anne is making a rockery on top of the tunnel, but Gillespie sees her and sends her back inside the marquee. Bea has to help Doreen free her leg , but she still isn't able to walk, so Bea goes back alone to try to get help. Margo and Hazel are worried that Bea and Lizzie haven't come back , especially when Vera notices that Bea isn't around, but Margo manages to cover for her. Bea reaches the entrance to the tunnel but can't get the lid up. Gillespie notices the ladder and raises the alarm: all the kids are sent home.
