The Universe is dangerously close to collapsing. With a shady authority known as the Time Police on their tail, will the Timeseekers be able to save us all? Their only hopes rest with the prophesied 'chosen one' who - rather unexpectedly - turns out to be a kind old lady called Barbara. However, Nana Barb, as she is affectionately known by her seven grandkids, one great-granddaughter and the members of her local bridge club, becomes lost in time after the physicist who lives next-door accidentally activates her new invention. Unfortunately the only people who can save Nana Barb (and the entire Universe) are her hapless grandson Dave, his best and idiotic friend Simon and the beautiful yet clumsy physicist Louise. Guided by the omnipotent tentacles of the Fates, Nana Barb ventures through time desperate for a good cuppa, in the process meeting her long-dead parents, spawning a new religion and picking up a futuristic android companion. Will Dave and his new friends shake off the deadly Time Police? Will the Timeseekers stop the Universe from collapsing? And more importantly, will Nana Barb ever find a decent cup of tea?
