One day, nobody dies. All across the world, nobody dies. And then the next day, and the next, and the next, people keep ageing – they get hurt and sick – but they never die. The result: a population boom, overnight. With all the extra people, resources are finite. It’s said that in four month’s time, the human race will cease to be viable. But this can’t be a natural event – someone’s got to be behind it. It’s a race against time as C.I.A. agent Rex Matheson investigates a global conspiracy. The answers lie within an old, secret British institute. As Rex keeps asking “What is Torchwood?” he’s drawn into a world of adventure, and a threat to change what it means to be human, forever.
Torchwood – 4×01 “The New World”
Earth is facing a phenomenon known as “Miracle Day”, where for over 24 hours nobody dies, and the world will become unsustainable to the soaring population within four months. Every United States Government agency receives a tip on Torchwood, only to later find every trace of the word deleted by the newly returned Jack Harkness, who discovers that he is now mortal. Separately, he and CIA agent Rex Matheson – who has suffered a ‘fatal’ accident but cannot die – travel to South Wales to find Gwen Cooper, who is living in exile with husband Rhys and infant daughter Anwen. Jack, Rhys and Gwen find themselves under attack by unknown mercenaries in a helicopter. After Jack saves them, Rex arrives and has Jack and Gwen extradited back to the United States.
Torchwood – 4×02 “Rendition”
As Rex brings the Torchwood team to America, problems arise on the plane: CIA operatives are plotting to remove them, and poison Jack, who is now the only mortal man on the planet. Gwen and Rex, with the help of Doctor Juarez, create an antidote. Meanwhile, Oswald Danes begins appearing on talk shows, generating buzz in the press and online after seemingly apologizing on national television. Upon landing, Rex and his colleague Esther find that they have been framed as traitors by an unknown party. Realising that they are being hunted, Rex and Esther join Jack and Gwen and go on the run.
Torchwood – 4×03 “Dead of Night”

Torchwood – 4×05 “The Categories of Life”

Torchwood – 4×06 “The Middle Men”
With Gwen, Rex and Esther trapped on both sides of the Atlantic, it’s a race against time as Jack goes straight to the heart of the conspiracy.

Gwen must fight to protect her family and takes a terrifying journey with Jack, covering both miles and decades, as the long history of the Miracle is beginning to be revealed.
Torchwood – 4×08 “End of the Road”
Jack faces a showdown with a man he thought was long since dead. But while Rex takes extreme action, is it too late to prevent the collapse of society?
Torchwood – 4×09 “The Gathering”
Two months later, and global recession has become global Depression. Esther nursed Jack to health and has been collecting blood samples from him in Scotland; Gwen continues to hide her father from police raids, while also selling stolen painkillers; and Rex is back working at the CIA; Jilly Kitzinger moves to Shanghai to work for the Families. Oswald Danes finds Gwen through the men who smuggled Jack into Scotland, forcing Esther and Jack to come to Swansea, where what Danes knows of Kitzinger’s activities leads them to conclude the Blessing is located in both Buenos Aires and Shanghai. Rex’s attempts to locate a descendant of a witness to Jack’s repeated murders in Little Italy are foiled by Charlotte at the CIA. Gwen is forced to take Oswald with them as she and Jack smuggle their way into Shanghai, where Jack’s blood is being physically pulled to the location of the Blessing. Esther meets up with Rex in Buenos Aires for their half of the mission, but they are being tracked by Charlotte.
Torchwood – 4×10 “The Blood Line”
At CIA HQ, Charlotte is able to protect her secret by blowing up Shapiro (John de Lancie) and Noah (Paul James). Rex and Esther face a setback when the suitcase containing Jack’s blood is blown up by a Family agent in the Buenos Aires military. Jack and Gwen strap Oswald to explosives to gain leverage over the Families, and learn that the miracle was caused when the Blessing — an unexplained rock formation controlling the morphic field — reacted defensively when introduced to Jack’s immortal blood. Rex reveals that he secretly transfused himself with Jack’s blood to keep it safe, meaning both agents are able to bloodlet into the Blessing at either end at the cost of their lives, thus ending the miracle. Esther is shot, but the group proceed. Gwen shoots Jack, knowing that she is effectively killing her father, him, Rex and Esther. With death restored, Oswald blows himself up along with a senior Family member (Frances Fisher); Gwen’s father passes. Jack’s immortality is restored; he resurrects and escapes the facility with Gwen. Some time later, Jilly is approached again by a Family agent (Teddy Sears) about assisting with their Plan B. Paramedics manage to revive Rex, but not Esther. At Esther’s funeral, Charlotte’s duplicity is revealed and she shoots Rex. To everyone’s shock, however, Rex displays Jack’s special ability, and instantly heals from his mortal wound.
