"What's the point of it all?" is a question humans have been asking themselves since the dawn of time. But as we cling to our dying planet, working round the clock while we're slowly being replaced by machines, now more than ever, people are desperately looking to make sense of their lives - before someone invents a computer that makes sense of it for them.

In this one-off extended special, Philomena will tackle some of the most complex concepts to have ever been discovered, including Quantum Physics, Existentialism, Nihilism, Hedonism - and at least four other isms - as well as exploring subjects from the big bang to biology, morals to meditation and art to artificial intelligence.

In her search for answers, she'll also examine the lives and works of some of history's foremost thinkers and ground-breaking creatives, from Epicurus to Dostoyevsky, from Sartre to Van Gogh, from Nietzsche to whoever came up with those signs in kitchens that say, 'Live Laugh Love'.

It's a journey that will take Philomena further afield than ever before as she visits sites of significance across Europe as well as travelling internationally for the first time to America (subject to visa approval but fingers crossed). Along the way, she'll be meeting leading experts and academics and not letting them leave until she's got to the bottom of such questions as: what is life, what's the point of life, why are we bothering to find out and when's lunch.
