Three people, two in a relationship Mitch and Alice, one gay friend Richie are on the verge of 30. Alice is first to turn 30 and all of them end up having a threesome in celebration of Alice's birthday. But the next day they find out that a wee surprise is waiting inside Alice's tummy. And after finding out that Mitch is not the father there's only one other person who could be... RICHIE!! But that's not the only surprise for Alice - Mitch is going to ask her to marry him!

And now our threesome have to figure out how to explain their unusually triangular relationship to the world. And most crucially to Alice's domineering and not entirely nice mother Lorraine (who is not fond of Mitch but adores Richie). Alice takes Lorraine off to dinner to break the bad news; she's marrying Mitch.

Alice, Mitch and Richie attend their first antenatal class. To everyones surprise Alice and Richie are hopeless and Mitch is an amazing proto-father. Alice and Richie go into panic mode about their suitability as future parents, and so Mitch entrusts them with a robot baby from the antenatal class to practice on. All they have to do is feed it, rock it, change it and not totally destroy it.

Mitch still hasn't got a job, and now his lack of funds is starting to become a problem. Alice needs reliable support more than anything right now the full reality of what's about to pop out of her in six months time is starting to hit home, and with the impending 12 Week Scan they're actually going to get to see their baby for the first time. It's time for Mitch to step up to the plate.

To Alice's amazement Richie and Dave are now dating. Proper boyfriends and everything. With Richie's birthday approaching a day of fun, fun, fun is being planned. But when Dave reveals he has alternative plans for Richie, tensions arise between the friends as Alice and Mitch conspire to keep Richie to themselves.

The mothers are coming. All the mothers; Mitch, Richie's and Alice's, all together, all for the first time. Alice, just a month from popping, has decided to throw a baby-shower, and so Lorraine (Alice's mum), Sue (Mitch's mum) and Jenny (Richie's mum) converge on the flat to deluge her with presents and attention. Alice in turn has taken to baking, not-swearing and dressing like a proper woman.

B-Day is nearly upon us. Just two weeks until Alice gives birth. To celebrate they throw a 'Final Push' fancy dress party - one last blast of chaos before the baby comes - to which Alice wears what is undoubtedly the finest pregnancy fancy dress costume of all time. Their friends are there, their mums are there - and Alice unexpectedly goes into labour early in the middle of it all.
