Each week, through their own selfishness and idiocy, we see Hannah and Dan — the worst brother and sister in the world — spectacularly wreck the lives of those around them — old friends, love interests, family members, and the unlucky individuals who just happen to cross their paths.
When her doctor tells her she is dangerously unfit, Hannah begrudgingly heads to the gym, using her father's membership. There, she meets Lucy, who introduces her to the world of women's rugby.
Jobless Dan has to be Aunt Leslie's dance partner at her local salsa class, as she's threatened to stop his allowance if he doesn't.
Hannah embarks on a dating frenzy after signing up to the latest new mobile app, but the guys she meets are never as hot or cool as their profiles suggest.
Hannah and Dan's irascible father, Gregg, has organised a birthday party for himself — something that Hannah finds suspiciously out of character. When Gregg announces that he's getting married to human rights lawyer Beverley, Hannah is upset that he hasn't discussed it with her.
At a coffee shop, Dan envounters Holly Freeman, his crush in circus camp when he was 14. The pair attempt to rekindle their relationship. However, Holly is eight months pregnant and the father is in Australia.
It's the wedding day of Dan's best mate Jack, and Hannah's joined as his plus one. Dan's ecstatic - he loves weddings, and this one's going to be pretty spectacular, as Jack is marrying the extremely wealthy Ophelia at their country mansion. Hannah can't wait to get snooping and see what life is really like for these Downton wannabes.
