Arthur wants to be a different person - to be in his Bondi era - but Maggie and bestie troublemaker Heather chain themselves in the way of his personal development.

When Arthur breaks both his wrists in a fall, Maggie has to look after the son who usually looks after her and in the process foils his attempt at instant internet fame.

Terrified that her memory is failing her, Maggie decides to throw a "70th Birthday to remember" and unwittingly drags Arthur and Robbie into a chaos they'd soon wish to forget.
