Travis Henderson (Harry Dean Stanton) is walking alone across a vast South Texas desert landscape. Looking for water, he enters a saloon and collapses. He is treated by a doctor (Bernhard Wicki), but does not speak or respond to questions. The doctor finds a phone number on Travis, calls the Los Angeles number, and reaches his brother, Walt Henderson (Dean Stockwell), who agrees to pick him up. When Walt arrives in Texas, he discovers that Travis is gone. When he finds him wandering alone, Walt tells his silent brother that he will take him back to Los Angeles. They stop at a motel, but Travis wanders off again. Walt finds him, and the two drive to a diner, where Walt begins to question the still silent Travis more forcefully about his disappearance. Walt and his wife, Anne (Aurore ClÃ©ment), have not heard from Travis in four years. After Travis abandoned his son Hunter (Hunter Carson), Walt and Anne took care of him for four years. Travis is visibly moved by the mention of his son, and tears flow from his eyes.Travis finally breaks his silence when he is looking at a map and remarks "Paris," talking about how he'd like to go there, although Walt mistakenly thinks that he is talking about France, telling him that it is a little out of the way. When Travis refuses to fly, Walt rents a car, and the brothers begin a two-day road trip back to Los Angeles. The next day, as the two brothers continue their journey, Travis shows Walt a weathered photograph of a vacant lot. He explains that he purchased the property in Paris, Texas, a town he believes is the place where he was conceived, based on a story told by their mother.When they arrive in Los Angeles, Travis meets Anne and the son whom he abandoned four years earlier. Hunter is uncomfortable around this stranger who is his father. Walt shows some old home movies, hoping to evoke good memories and help break the ice between the father and son. The movies show Travis with his wife, Jane (Nastassja Kinski), and their young son, sharing a day at the beach.In the coming days, the relationship between Travis and his son slowly grows, and a bond of trust between the two starts to develop. Anne tells Travis that although she has not heard from Hunter's mother for a long time, she still deposits money into a bank account for her son on the same day each month. She reveals the name of the bank in Houston, where the deposits are made. Travis becomes determined to find his lost wife, and when he tells his son that he plans to travel to Houston to find his mother, the boy says he will accompany him.Travis and Hunter leave for Texas without telling Walt and Anne. During their journey, Travis and Hunter grow closer, with Hunter sharing things he learned in school, and Travis sharing his memories. When they arrive in Houston on the expected day of deposit, Hunter spots his mother leaving the bank. They follow her to a parking lot of a peep show club. Telling Hunter to wait in the car, Travis enters the club, containing rooms where customers sit behind one-way mirrors and tell the strippers what they want to see via telephone. The women cannot see the customers. Travis is shocked, but ends up in a room opposite Jane. After several minutes of awkward silence, Travis walks out, returns to the car, and drives to a bar, where he begins to drink.The next day, Travis drops Hunter off at the MÃ©ridien Hotel in downtown Houston, and heads back to the club. Travis enters a room with Jane on the other side of the one-way mirror. He picks up the phone, turns his chair away from her, and tells her a story of a man and a young girl who fell in love, married, and had a child, probably before they were ready. At first, Jane is confused by the story, but she soon realizes who is on the other side of the glass, and that the story is that of their relationship. Travis describes how the couple's love turned from being joyful to stifling, explains how the drunken man suffocated the young girl with his jealousy and control, and tells how he came to loathe himself and why he disappeared to a place "without language or streets" â never wanting to see anyone again.When Travis prepares to leave, Jane urges him to stay. She tells how hard it was to leave him, that for years she thought of him often. Travis finally faces the glass, turns a lamp on his face so Jane can see him, and tells her where she can find Hunter, asking her to go there and reunite with her son. Jane agrees and Travis leaves the room. Later that night, Jane enters the hotel room where Hunter is waiting, and they reunite at last. Travis watches from the parking lot and then leaves Houston behind him, driving alone., Question: How many years ago did Travis abandon his son?
