With the first and only boy Pandora’s ever fancied having been deported, Pandora is desperate for some fun and decides to throw a party. Unknown to Pandora, Katie has used some special ingredients in the chocolate brownies, which take the party to another level. Effy knows, but hasn’t warned Pandora or her mum Angela (Sally Phillips), who is munching happily on the choccie treats. Effy can only look on while her best friend’s mum’s behaviour gets increasingly bizarre. Pandora grabs the fun where she can, and towards the end of the evening lets her heart rule her head… but will she regret it in the morning, and will her best mate forgive her? Also guest starring (David Baddiel) as Steve, and (Harry Enfield) as Jim Stonem.
