Stress levels are through the roof during exams at Erinsborough High, but the disappearance of Year 12 student Olivia Lane has got everyone on edge. Fortunately, the task of recording a private video diary for view at the ten-year reunion is giving respite to students as they make sense of the chaos. Yashvi has finished her last exam and is determined to celebrate – but is it all just for the camera?
Having found the missing Olivia, Yashvi assumes she got spooked by seeing Finn Kelly on campus. Olivia doesn't deny it, and Yashvi agrees to provide her refuge on Ramsay Street. But when she spies a cryptic love text on Liv's phone, Yashvi begins to suspect she's running away from someone other than Finn. When she later spies Olivia getting into a car with a teacher, Yashvi's rocked. Could they be Olivia's secret lover? After witnessing his tormentor's warped respect for Hendrix, Jeremiah realises an alliance with Hendrix could be a form of protection. Meanwhile, Richie feels the pressure to ace the Physics exam, and the temptation to join up with Hendrix is strong.
It's exam time, and Hendrix is apprehensive about the plan – but he's saved from having to pull out himself when Richie wants out. They spread the word among the other students, but Jeremiah keeps his bully Ollie in the dark. Hendrix throws a party at Lassiters to prove he's still a legend and invites Jeremiah. But Ollie gets to him first… Mackenzie is happy to hear Richie pulled the plug on the plan, but she remains confused by his inability to talk to her in real life. Meanwhile, Yashvi comes to think the worst about Liv – especially when she finds a pregnancy test in her locker.
Anonymous texts begin to circulate about the relationship between Olivia and a teacher. Humiliated, Olivia accuses Yashvi of being the source. But her stomach turns when she realises the person responsible for the rumour is the person she's in a secret relationship with. Mackenzie's on a high after kissing Richie, but she's devastated when he yet again blanks her at school. Meanwhile, Hendrix seeks out Jeremiah to tutor him next year and is shocked to see the damage that Ollie has inflicted on him.
Learning Richie and Olivia had been having sex, Mackenzie is filled with anxiety over her new boyfriend's expectations. Meanwhile, Hendrix decides to take a stand against Ollie and report his assault of Jeremiah – putting his reputation and new friendship in jeopardy. Olivia's lover begs her to remain silent about their relationship until she's finished her exams and can leave home. Seeing Olivia's distress, Yashvi makes it her mission to help her friend, and as a result finds a career path worth pursuing post-high school.
