Two 19-year-old homebodies head off to the Greek party town of Kavos.
Ollie lives in Bath with mum Debbie and ex-army dad Alan, who do everything for him. He has found himself in a directionless rut since his 'A' levels and is currently working in the family-run garage, but is less than enthusiastic about it. He wants to use this holiday to figure out what he wants to do with his life and let loose with his mates Cameron, Kieran and Dan.
In Basildon, part-time student Katy is preparing for her first holiday away from her overprotective parents Terry and Susan. Going away on her own is a big deal for Katy, who rarely leaves Essex. Usually very responsible, she always lets her parents know what she's doing on a night out and they believe that she rarely ever drinks. She's heading to Kavos with friends Charlotte, Lacey and Kellie.
On the first night the Bath boys get tanked up in their room on numerous shots before heading out, but their drunken behaviour gets them in trouble with hotel security before they've even hit the bars. The girls arrive on the strip and Katy's first priority is booze, but after several hours of drinking she isn't faring too well and ends up throwing up on the street. Things are a lot worse for Ollie's group however, as Kieran passes out completely and an ambulance needs to be called.
Little do the teens know that their parents have landed on the island and are driving past them in a van. As they watch their children's antics Katy's parents become emotional when they realise that their little girl is all grown up. Ollie's parents are hoping that he'll have learnt a lesson from his friend's mistake, but on the second night it's not looking good.
