After returning to her hometown of Roswell, New Mexico, Liz, the daughter of undocumented immigrants discovers her teenage crush is an alien who has kept his unearthly abilities hidden his entire life.

She protects his secret as the two reconnect, but when a violent attack points to a greater alien presence on Earth, the politics of fear and hatred threaten to expose him.

Max and his partner Jenna identify a local, Wyatt Long, as the man who shot Liz, and embarrass him in a shooting contest.

Kyle agrees to help Liz find her sister's hidden autopsy report, which reveals that she did not die in an accident.

Michael strikes up a relationship with Alex Manes, a veteran working near his trailer, while Max has sex with Jenna at her house.

After Kyle sees an injury on Liz caused by Max's abilities, he secretly copies his father's research on aliens for Project Shepherd.

Jesse, Alex's father and a member of Project Shepherd, presses Jenna for access to Sheriff Valenti's files.

Liz finds a recording from the night her sister died with a local documentarian, Grant Green, saying that he saw "floating people", but when she confronts him, he runs off.

Kyle and Alex uncover a vault belonging to the late Jim Valenti that he used to keep Rosa safe while he helped her detox from her addiction.

Isobel grows closer to Rosa, who wants to leave town so she can get clean, and disappears that night, sparking an argument between her brothers and her.

In 1947, Project Shepherd conducts an autopsy of a deceased alien, discovering a strange symbol on its hand, which matches one on Max's back.

Max is reinstated as a deputy, but denied permission to return to active duty, and Liz agrees to help Maria with her mentally ill mother Mimi, who believes in the existence of aliens, which she frequently confuses with the plot of Independence Day.

Mimi gives Alex a vague warning about not ending up like Jim Valenti and his father, and mistakes Liz for Rosa, which she plays along with to gain her trust.

Max discovers that Liz has been conducting experiments using his DNA to develop a serum that neutralizes alien powers; Isobel, wracked with guilt, agrees to be placed on a temporary psych hold.

Max asks Liz to continue working on the serum in the hopes that it might allow his siblings and him to lead normal lives.

Kyle learns the truth about Rosa's death from Liz, and injects Isobel with the untested serum, which she claims was partly because she influenced him to do so.

With no other options, Liz turns to alien research conducted by Michael in secret, which leads her to conclude that Isobel can only be saved by using the pods to keep her in suspended animation.

Jenna asks Alex and Kyle about what she thinks is a police coverup concerning several mysterious deaths, and they reveal to her the existence of aliens.

Liz tells Max that all signs point to a fourth alien in Roswell, who may possess knowledge of his home world.

Alex and Kyle use the piece of husk the former found to decode a secret message left by Jim Valenti, which references Caulfield, an old state prison.

As the town prepares for the UFO Emporium reopening gala, Max asks Liz to be his date, but she declines, since she needs to accompany her father.

Michael comes up with an alien pacemaker to keep Max alive and, when it seems he will still die, Rosa demonstrates alien-like abilities to charge the defibrillator and revive him.

However, they come flooding back after he finds the bullet she was shot with and the couple spend the night together on the roof of the Crashdown before she tells him she loves him.

Arturo gives her his mother's ring in exchange for the contract and Max later retrieves it by threatening to reveal her past to her politician boyfriend.

Michael and Kyle look into Maria when she starts receiving visions and discover her grandmother was part of an experiment to try and give people alien powers.

In the present, Alex takes Max, Michael, Isobel and Maria to the reservation, where his mother came from and his brother Gregory lives.

Michael realises Helena is swapping it for one that will kill Manes and his family, in revenge for Jim's murder, so leaves Alex behind as a prisoner.

Jenna gets Maria to the hospital (where she is saved by Liz's serum), Charlie is rescued by Helena and Gregory kills Manes when he tries to shoot Michael.

Michael and Alex find Tripp's body buried under the Manes shed and that he left Mimi a journal, which reveals a stowaway, Mr. Jones, caused the ship to crash and attacked the soldiers, prompting the massacre.

The website's critic consensus reads: "Roswell, New Mexico admirably adds modern political context to its premise, but this reboot hews too closely to its predecessor to transcend the pitfalls of a redundant retread.
