It’s a pivotal point in both their lives, bringing to the surface those all-important questions – could sleeping with your former History teacher be the key to happiness? Is a basement Rat Hotel a functional alternative to pest control? How do you stop your new psychiatrist giving you worry dolls? With their twenties behind them, Maggie and Eddie’s relationship faces the future – can it survive?
