It stars Storm Reid, Joaquim de Almeida, Ken Leung, Amy Landecker, Daniel Henney, and Nia Long.

An anthology sequel to Searching was announced in 2019, with Merrick and Johnson, who edited the first film, signing on to make their directorial debuts in January 2021.

Reid and Long joined the cast in the spring of 2021, and filming took place in Los Angeles from March to May that year after delays due to the COVID-19 pandemic.

Missing also serves as a spiritual sequel to Run (2020), directed by Searching director Chaganty and edited by Merrick and Johnson, confirming the fates of that film's characters.

As the epilogue of Searching that's been adapted on the true crime show Unfiction is being played on her computer, 18-year-old June Allen lives with her single mother, Grace, in a suburb of Los Angeles.

June cracks the password to Kevin's Gmail account, in which she discovers several aliases and a criminal record of scamming many women for their money.

June quickly unmasks this as a fabricated event, as she discovers Kevin had hired a lookalike actress named Rachel to impersonate her mother, who had been kidnapped en route to LAX beforehand.

Checking through her blocked users, she finds a threatening e-mail directed at Grace, which leads her to discover security cameras Kevin bought to install at an abandoned house, which happens to be her old vacation home in Nevada.

It is revealed James was a drug addict whose abuse endangered his family, and Grace had told June he died of cancer to protect her.

James sought revenge by enlisting Kevin, whom he met in prison, to pose as a prospective boyfriend so he could find Grace and June.

June, realizing James never shut off her laptop when he kidnapped her, uses the audio feed on the security cameras to tell Siri to call 911 for their rescue.

The website's consensus reads: "Missing can strain credulity in its efforts to keep the audience guessing, but a fast pace and relatable fears keep this twisty techno-thriller from completely losing its way.
