List of The Leftovers episodes

The series features an ensemble cast that includes Justin Theroux, Amy Brenneman, Christopher Eccleston, Liv Tyler, Chris Zylka, Margaret Qualley, Carrie Coon, Ann Dowd, Regina King, Kevin Carroll and Jovan Adepo.

It begins three years after the "Sudden Departure", a global event that resulted in 2% of the world's population disappearing, and follows the lives of those who were left behind.

It takes place primarily in the small town of Mapleton, New York, three years after the "Sudden Departure" – an event which saw 2% of the world's population (approximately 140 million people) disappear and profoundly affected the townspeople.

The characters of police chief Kevin Garvey and his family (wife Laurie, son Tom, daughter Jill and father Kevin Sr.) are focal points of the season, alongside grieving widow Nora Durst, her brother Reverend Matt Jamison, and the mysterious cult-like organization the Guilty Remnant (GR), led by Patti Levin.

The first season follows multiple storylines, notably the fallout from the Departure and the subsequent grief, anger and fear the townspeople share with the rest of the world.

The town has become a tourist site and a popular destination, leading Kevin, Nora, Matt and other characters from the first season to move to Miracle.

New characters introduced include town staples the Murphy family: father John, mother Erika, daughter Evie and son Michael.

The second season follows multiple storylines, notably the ideological battle between those who believe Miracle is special and those who do not, Kevin and Nora's relationship being tested by Kevin's increasingly erratic mental state, the Murphy family's search for their missing daughter, and Matt's attempts to prove the existence of a miracle only he witnessed.

The third season follows multiple storylines, notably Matt and Kevin Sr.'s belief that the seventh anniversary of the Departure will bring an apocalyptic flood in Australia, Kevin coming to terms with his apparent immortality and coming to believe that it is his destiny to prevent the apocalypse, and Nora grappling with a scientific discovery that could reunite her with her family.

Nora is contacted by actor Mark Linn-Baker, who claims he represents people who can reunite her with her children if she meets him in St. Louis.

Nora meets with Linn-Baker but is convinced he is suicidal after he explains the group he represents have built a radioactive machine which can theoretically "send" people wherever their departures have gone.

In Australia, a group of women kidnap a police chief named Kevin and drown him, expecting him to return to life.

After arriving in Australia, Kevin sees Evie outside a window in a television studio in Federation Square and races there to confront her.

Kevin ignores her and finds "Daniah" at a public library, leading Laurie to force him to realize that the girl is not Evie and that he has been hallucinating.

A Marine Nationale submariner launches a nuclear weapon at an island in the South Pacific Ocean, leading to all air traffic being grounded.

The grounding of flights forces the party to land in Tasmania and board a passenger ship (which is hosting a "pride" of people that celebrate the lineage of "Frasier, the Sensuous Lion" through mass copulation).

The mystery man from the realm of the undead is onboard, revealed to be someone named David Burton who claims to be God.

Nora hesitates, unable to decide what to do, and Laurie tries to persuade her to do her job and report the fraud to the DSD, implying that the machine cannot take her pain away.

Kevin is alerted that there is an imminent nuclear threat and goes to a military bunker to plan a response, aided by his Secretary of Defense (Patti).

One day, an older Kevin arrives at her doorstep, seemingly unable to remember anything that happened between the two other than the time they met at the school dance.
