Two families on one lake
Caddo Lake is a Max original film of 2024, written and directed by Celine Held and Logan George, with M. Night Shyamalan among its producers. It runs one hour and 44 minutes. Max sums it up as the story of eight-year-old Anna, whose disappearance changes a family history already broken by past deaths and disappearances.1 Collider gives its date on Max as 10 October.2
The Caddo Lake family tree has two halves that seem to have nothing to do with each other. One is the household of Ellie in 2022. The other is Paris Lang, a young man who lost his mother on the lake and who is first seen in 2003.25 The film cuts between the two, and the viewer learns only near the end that they are one family.
The directors told Nerdist that the time travel in the film is a natural phenomenon of the lake, with no one behind it. The story grew out of Logan George’s grief for his late mother and a question about how well anyone knows their parents.8 The chart keeps to what the film shows and does not explain the slips.
Ellie’s side of the Caddo Lake family tree in 2022
In 2022 Ellie lives with her mother Celeste, her stepfather Daniel and her younger stepsister Anna, who is eight.26 Anna is Daniel’s daughter, and Celeste is her stepmother.6 Game Rant and Collider both call Anna Ellie’s stepsister, not a half-sister, so the two girls share no parent in the present.72
After a fight between Ellie and Celeste at the dinner table, Anna vanishes on the lake and a search begins.2 On the chart Ellie and Anna are joined by a teal dashed arrow labelled Searches for, which runs from the day Anna disappears.
Ellie does not know who her father is when the film begins, and she learns it only on her trip into the past.4 The chart therefore draws her under Celeste alone at the 2022 point, and the line from her father appears only when the film reveals him.
Paris Lang and his parents on the Caddo Lake family tree
Paris is the son of Ben Lang and of a mother the film keeps unnamed for most of its length.4 In 1999 her car went off a bridge into the lake with Paris inside. He survived and she drowned.35 The official cause was a seizure at the wheel, and Paris doubts it.37
In 2003 a young woman called Cee comes back to the lake. She and Paris become close, and she becomes pregnant.5 Paris works out that low water opens passages in time, enters one, and is presumed missing.5
The chart draws Paris’s mother with a question mark until the film reveals her, and Cee as a separate woman until 2005. Ben is the one adult in the loop who never travels in time.4
How the Caddo Lake family tree closes into a loop
Searching for Anna, Ellie slips back to 2005, where she meets the young Cee holding a baby. The baby is Ellie, Cee is Celeste, and Paris is Ellie’s father.43 On the chart Cee merges into Celeste at the 2005 point, and a parent line from Paris to Ellie appears. Held told Nerdist that Paris and Ellie never knew who each other were.8
The second reveal turns the chart over. Anna came out of the lake in 1952, injured, and Paris found her and brought her to safety.45 She stayed, grew up, married Ben Lang and had Paris, so the girl Paris saved is his own mother.47 She was the woman who drowned in 1999, at the age of 55, after 47 years in the past.57 On the chart Paris’s mother merges into Anna at the 1952 point, and Anna takes the cross of that death.
Read down from Daniel, the loop runs through four generations. Daniel is Anna’s father, so he is Paris’s grandfather and Ellie’s great-grandfather as well as her stepfather.4 Anna is Ellie’s stepsister in 2022 and her grandmother by blood.4 Ben is Ellie’s grandfather through Paris.4 A Caddo Lake family tree drawn in one direction cannot show this without a line that runs back up the page, so after the reveal the line from Anna climbs to Ben and to her son Paris.
The ending closes the passages. Paris comes out of the lake in 2022, is arrested, and jumps from the dam. The dam breaks, Paris drowns, and the slips in time end.53 Ellie shows her mother Anna’s school picture from 1952 and tells her that neither Anna nor Paris meant to leave them.6

Where the explainers of the film disagree
The film gives few dates on screen, so the explainers differ on some. Most put Ellie’s trip in 2005, while Screen Rant’s ending explainer places the scene with the baby in 2003.56 Screen Rant’s family tree puts Ellie’s birth around 2002, which cannot be right if Cee only became pregnant in 2003, and its timeline points to about 2004.45 The chart gives no birth years for that reason.
Collider’s ending explainer calls Anna Celeste’s daughter in one place, against its own review and every other source, which make her Celeste’s stepdaughter.32 The cast list credits Gina Limbrick as the mother of Paris, the adult form of Anna in the scenes of 1999.9
How to read this Caddo Lake family tree
A square is a man and a circle is a woman, and Ellie carries the double outline of the person the chart follows. A solid line is a marriage and a dashed line a couple who were not married. A dashed line down to a child, as from Celeste to Anna, is a step relation.
A symbol with a question mark is a person the film has not revealed yet. When Story position reaches the reveal, that symbol merges into the person it turns out to be, and its lines move with it. The teal arrow from Ellie to Anna is the search, and the grey dotted line between Paris and Ellie marks the meeting of two people who do not know they are father and daughter.
