Dive: Lindey's Story on BBC Two

With British teen pregnancy on the rise, there's an increasing scrutiny on exactly what it is we're telling kids about all that stuff. Sex education lessons seem to be starting younger and younger, but it also seems that the mums are getting younger and younger. Dominic Savage's two-part drama, Dive, indicates that the problem doesn't lie so much with the kids' education as with their attitude.

Co-written by Savage and Simon Stephens (Punk Rock, Herons, Pornography), Dive opens up a group of teenagers who know how sex works – they've had the lessons, seen (and laughed at) the videos, got the T-shirt and avoided parents' questions. There's a brilliantly subtle moment to watch out for, when the biology class pair off to practice putting condoms on ominously-entitled 'demonstrators'. Main character Lindsey (Aisling Loftus) contemplates hers for a moment – over her shoulder, and just out of focus, her friend (Chanel Cresswell) slips one on in seconds and proudly announces “Perfect”. Someone's done this before...

So, they know what they're doing. It's their casual, carefree attitude that's the problem. Watch as Robert (Jack O'Connell) dashes off into the sea, telling his (girl)friend to leave her clothes on the beach – pregnant and likely to catch her death of cold. And not long before that, he'd been diving into a pool with just boxers on...what an irresponsible young man, no wonder he got her pregnant. Call me old-fashioned, but teenagers having a quickie up against a tree with someone they've just met doesn't seem to indicate that sex education is encouraging responsible or safe sex.

We're probably going to see an increasing amount of drama with some focus on the 2012 Olympics in the next two years. This is one that's been put together really well, with some beautiful shots and a careful balance between Lindsey's dreams of representing Britain at the Olympics (as a diver...obviously) and her life at home – watch out for Gina McKee, sensitive as ever, and Joseph Mawle as the resented-yet-caring step-father, to say nothing of Ewen Bremner's sweet turn as Lindsey's dad. There's plenty of 'mood' all round, with lots of lingering shots of diving bodies, sparkling lights and brooding teens, all with gently sentimental music layered over it.

We'll have to wait for Robert's side of it in the next episode, but somehow I don't think a baby is quite the Olympic legacy either of these two wants.
