In the Shadow of the Moon is a science-fiction crime thriller that premiered on Netflix on September 27, 2019, six days after its world premiere at the Fantastic Fest film festival. Directed by Jim Mickle, the film weaves together elements of mystery, time travel, and social commentary across multiple decades of narrative storytelling.

The story follows Philadelphia police officer Thomas Lockhart, played by Boyd Holbrook, as he investigates a series of inexplicable deaths in 1988 that spiral into a decades-long obsession. What begins as a straightforward murder investigation evolves into something far more complex when the truth behind the killings emerges. The film received moderate critical reception, with praise for its ambitious premise and visual elements, though some critics noted uneven execution and pacing throughout its 1 hour 55 minute runtime.

In the Shadow of the Moon Explained

The film opens in 1988 Philadelphia, where several individuals simultaneously hemorrhage to death with disintegrating brains and massive blood loss. Police officer Thomas Lockhart discovers the victims share puncture wounds and identifies a black woman with a wounded hand as the suspect. When Lockhart confronts her in a subway station, she reveals intimate knowledge about his personal life, including that his wife will give birth that day. She predicts her own death before a train strikes and kills her. Tragically, Lockhart’s wife dies in childbirth, establishing the emotional foundation for his subsequent obsession.

The Nine-Year Cycle

Nine years later, an apparent copycat begins killing again using the same mysterious method. Lockhart, now working as a private investigator, discovers keys from 1988 that trace to an aircraft manufactured in 1996—evidence suggesting time travel played a role in the original killings. Shockingly, he encounters the same suspect from 1988, who hasn’t aged a single day. Through his investigation, he learns the suspect targets members of white nationalist militia groups, positioning her as a vigilante operating outside conventional justice.

The Time Travel Revelation

By 2015, physicist Naveen Rao reveals he developed the killing technology—an injection triggerable through time. The truth emerges: the suspect is Rya, Lockhart’s granddaughter and Amy’s daughter, traveling backward in time to eliminate those who will inspire future tragedies. The key revelation comes when Lockhart realizes he himself killed Rya in 1988 during their subway confrontation. Convinced her cause is just, he chooses to allow her mission to continue.

Plot Detail

The film employs a nine-year cycle structure, with events repeating across 1988, 1997, 2006, and 2015. This cyclical pattern reflects Rya’s repeated journeys through time, each targeting individuals identified as future threats to society.

Narrative Structure

The twist relies on Rya being Lockhart’s granddaughter, creating a generational paradox. His choice to allow her mission means accepting his own role in her death during their first encounter, while simultaneously enabling her survival across subsequent timelines.

Spoiler Alert

The 2024 sequence reveals that an elderly Rao triggers the injections, killing Rya’s targets and erasing her timeline entirely. Lockhart ultimately reunites with his family in 2015, embracing an altered future free from the tragedy that defined his original life.

The Film’s Context and Significance

In the Shadow of the Moon occupies a unique position within the science-fiction thriller genre, blending investigative crime procedural elements with philosophical questions about fate, choice, and temporal responsibility. The film draws comparison to other time travel narratives that explore the consequences of altering history, though it distinguishes itself through its focus on a generational family saga spanning multiple decades.
