Sadie, Hannah's best friend from university, has returned from travelling and Hannah could not be more excited. Dan, however, couldn't care less - he's planning to watch all the Liam Neeson films back to back, or as he calls it, The Liam Neeson Seeson. But Sadie has a surprise for Hannah - she's engaged. Her fiancé Rich is funny, charming and full of anecdotes about his time as a vet tending to animals in exotic faraway countries. Hannah, naturally, hates him and so decides to remind Sadie how good her life was before she met Rich - ie when she was hanging out with her at uni. Rich offers Dan a receptionist's job at his vet practice, but he gets overly involved in the animals' well-being, taking matters into his own hands.
