Alice turns 30. The three have a drug-addled threesome. Alice gets pregnant. She and Mitch decide to get rid of it. Mitch changes his mind. Mitch and Richie race to stop Alice at the clinic. More happens but that would spoil it before you see it.

Mitch and Richie use drugs as a force for good and put up all the flatpack furniture in the nursery while high as a kite.

The threesome attend their first antenatal class, and Alice and Richie experience serious doubts about their suitability as future parents.

When Alice's tall, handsome and rich ex, Ben, turns up it sends Mitch's pre-existing insecurities into overload.

It's Richie's birthday and new boyfriend Dave has special plans. The trouble is that Alice has her own (more special) plans... as does their unborn baby.

The mothers are coming! All the mothers; Mitch, Richie's and Alice's, all together, all for the first time.

The threesome prepares for Alice's 'Final Push Party' with some questionable costume choices from the boys.
