Half term may be over but the chaos has just begun.

Mr Logan has run off and eloped with Miss Sharkreve leaving the Lower Sixth with a new housemistress - the tyrannical, catty Mrs Dicks. And with the rules getting tighter at St Cecilia's, the students are getting way more creative in finding ways to break them - especially as they''re all feeling a bit frisky.

Tally, broken hearted and on the rebound, sets her sights on safe bet Rando, while Alice and Tristan decide to take their relationship to the next level. Things between Dylan and Jasper are seriously heating up - could she finally have found a guy who won''t disappoint her?

As tensions reach an explosive high, a pool party at Rando''s country estate should be just the thing to cool everyone down. Or will it push the temperature up a notch?
