Michelle and her friends are living through their twenties as bravely as they dare.

On a mission to gain life experience before reaching the age of responsibility, Michelle hosts a Wild West themed threesome, Grant rides a cow through the city centre, Chris goes backpacking around his own neighbourhood, and Alex plays at ghostbusting with Michelle's friend Jenny - all as the group continue their headlong rush to explore sex, identity and friendship before they hit thirty. Even the discovery that Chris is a father doesn't slow them down.
