Us is the new BBC One TV series - here's all you need to know.
Us is a four-part adaption of the popular novel of the same name by David Nicholls.
A synopsis of the show reads:
Douglas Petersen is blindsided when his wife Connie tells him that she’s not sure she wants to be married to him anymore. Agreeing to still go on their planned family grand tour of Europe, Douglas vows to win back the love of his wife and repair his troubled relationship with their son Albie.
Reflecting David Nicholls' signature mix of humour and heartbreak, Us brings the Petersens' poignant and often hilarious story to life, taking viewers with them on their once-in-a-lifetime journey through some of the most beautiful cities in the world.

David Nicholls, who wrote the book and is adapting it for the screen, said: “It’s a huge thrill to see the novel come to life, and with such a wonderful cast and production team.
"We want to make something funny, touching and beautiful, to really explore marriage and family life, all against this incredible backdrop.”
Tom Taylor (Doctor Foster, The Dark Tower) plays Albie.
Further casting includes Sofie Gråbøl (The Killing, Fortitude) as Freja, Iain De Caestecker (Agents of S.H.I.E.L.D, The Fades) as young Douglas and Thaddea Graham (Curfew, The Letter for the King) as Kat, Gina Bramhill as young Connie.
In episode 4 (October 11), when Douglas (Tom Hollander) and Albie (Tom Taylor) come face to face in Barcelona, Douglas tries to make amends for his actions. Albie prepares to give his dad another chance - but disaster soon strikes.
Will a near-death experience, the unearthing of secrets, and Douglas’ dogged determination to keep his family together be enough to change Connie’s feelings?
Life, as he knows it, feels like it’s coming to an end...
