It stars Frank Grillo as a retired special forces soldier who tries to escape a never-ending time loop that results in his death.

He has been able to elude more assassins throughout the morning, but finds himself unable to figure out how to survive a final attack at 12:47 PM, waking up back in his apartment on the next loop.

Through more trial-and-error loops, Roy finds a way to remove the tracker and sneak into Dynow, killing several guards and assassins, but is always stopped by Ventor and the sword wielding Guan Yin.

Jemma tells Roy that he has to enter the Osiris Spindle in order to reset it, and that either he would wake up and repeat the day once more or die and stay dead.

In addition, Sheaun McKinney plays Dave, the counter surveillance expert, and Armida Lopez plays Esmeralda the chauffeur while the remaining assassins are: Buster Reeves as Mr. Good Morning; Eric Etebari as Roy #2; Quinton "Rampage" Jackson and Rashad Evans as the German Twins; Adam Simon as Loudmouth; Aaron Beelner as Marshall / Kaboom; and Michael Tourek as Smiley.

Blumhouse asserts that they were brought in to recut the film after the original version failed to secure distribution, but have not been compensated for their work, which was to be 5% of the acquisition fee paid by Hulu.

The site's critics consensus reads: "Boss Level powers up the increasingly crowded time-loop genre with a gleefully over-the-top sci-fi action thriller that revels in its own excess.
