The second series continues to see brother and sister Dan and Hannah plumb the depths of bad behaviour - wrecking marriages, breaking apart families, and creating chaos in the workplace. Run into Dan and Hannah and you are very unlucky indeed. Over six excruciatingly funny episodes, Dan and Hannah create chaos everywhere they go. Hannah finally finds her calling as a corporate downsizer, firing colleagues with wilful abandon; becomes determined to destroy her nemesis on a women's rugby team, and plots to get rid of the beautiful best friend of her new boyfriend. Meanwhile, Dan begins an ill-advised friendship with a terminally ill man, is embroiled in a dangerous kidnapping and ruins a wedding when he becomes a last-minute best man.
