 Julie Corrigan s mother forces her reluctant daughter to go to school. She arrives with a sick note, but is met by Alice at the gates, who promptly tears it up. Mrs. McClusky tries to squeeze money out of Mr. Hargreaves s advertising revenue to help pay for a forthcoming trip to Russia. Nick and Richard find out that the expected money for the trip isn t available, and that Matthew is one of those who would be unable to go without financial support. They decide to hack into the Deputy Head s computer to see what the real state of school finances really is. Alice starts spreading a rumour about Chrissy s pregnancy, saying that Mr. Van Der Groot is the father, because she s been seen going round to his flat. Justine overhears the conversation, and confronts Chrissy, who denies it. Justine pulls Fran out of her lesson (on the pretence of her needing to speak to Mrs. McClusky) and the three try to work out how the pregnancy has become common knowledge, and who started saying it was Mr. Van Der Groot. After Fran leaves, Chrissy tells Justine that she s going to a special clinic to have her pregnancy confirmed. Richard logs on to Mr. Hargreaves computer, but can t find the advertising money accounted for. Believing that the Deputy Head has done some rather creative accounting, he eventually finds it under the refurbishing accounts, and just manages to pull a name "O  Hanlon" off the computer, before Matthew warns him that the deputy head is approaching. In the canteen, Justine and Natalie are a little too loud in their discussion about Nat s sister Becky being the one who spread the rumour - and Mr. Mackenzie overhears their conversation. Discussing what they see as an unjust use of the advertising revenue, Richard suggests they use another computer, since all school machines are networked together. Matthew fakes an illness in the receptionist s area, so Nick and Richard can access the computer in there. Richard starts the printout going, but it s too slow, and the receptionist returns before he can collect it. It s Trevor who finally breaks the distorted news to Ted about Chrissy, telling him that she s pregnant, and the Dutch teacher is the father. Back at the receptionist s area, Mrs. McClusky finds the printout, and takes it, immediately realizing its significance. She calls in Mr. Van Der Groot, and asks him to elaborate what s been happening with the Fourth Form girls. He protests innocence, pointing out that Chrissy s boyfriend appeared after she had been helping with the decorating. Unsupervised in their classroom, Alice and Robyn offer a rather doubtful olive branch of peace to Julie - they will be friends with her, but only if she passes the test of jumping in the swimming pool with all her clothes on. To their astonishment, she determinedly sets off. She arrives at the pool, with Mr. Robson taking a class there, and to everyone s astonishment she takes the plunge, to the bewilderment of the teacher, and the merriment of the occupants of the pool. In the Head s office, Mrs. McClusky has it out with Mr. Hargreaves over the fraudulent use of the advertising money. At the end of the school day, Ted finally manages to get a word with Chrissy, who s not happy that he believes that the Dutch teacher could have gotten her pregnant, and she storms off...
