In Release-Date Order: A Closer Look at September 2026’s Featured Titles
Below are the synopses and highlights for each title, listed in order of release date.
The Runner
- Release Date: September 2, 2026
- Original Title: The Runner
- Country of Production: United States, United Kingdom
- Genres: Movies / Action, Suspense, Thriller
- Director: Kevin Macdonald
- Cast: Gal Gadot, Damian Lewis, and others
【Synopsis】
Maia Marten (Gal Gadot) is a high-powered lawyer at the top of London’s legal world. During her usual morning run, a phone call shatters her routine: her son has been kidnapped. To get him back, she must keep moving, follow every command, and tell no one. Forced to race through the streets of London, Maia obeys a series of increasingly dangerous instructions as she fights to save her son.
[Highlights] A nearly nonstop race-against-time thriller sparked by a single phone call. London itself becomes part of the tension as Maia is forced to keep moving, with every decision shaped by one goal: saving her son.
Why Bob's Pick?
Gal Gadot’s lead role brings plenty of attention, but the film’s biggest hook is its brutally simple premise: Maia cannot stop running. With September’s Prime Video lineup leaning heavily into romance and series, this standalone race-against-time thriller offers something distinctly different.

【Synopsis】
Yukio Akashi (Akapen Takigawa), a technical specialist at the Tokyo Metropolitan Police Department’s Investigation Records Management Center, receives a cassette tape from an unknown sender. On it is a mysterious instruction: “Investigate Shunsaku Aoshima’s missing 13 years.” With no investigative authority and no personal connection to Aoshima, Akashi begins tracing his movements from 2013 to 2026 using a vast archive of investigative records as his only clues.
[Highlights] This new spin-off explores 13 previously unseen years in the story of Shunsaku Aoshima. Akashi follows the clues through investigation records, imagination, and deduction. The series also connects the previous film with the newest movie.
Ahead of the September 18, 2026 theatrical release of Bayside Shakedown N.E.W.: Race Through Metropolis!, this new series is worth watching for the way it fills in 13 previously unseen years of Shunsaku Aoshima’s story. With only three episodes, it also makes for an easy catch-up before the latest film arrives.
