Boss Level (2021) Timeline Explained – Every Event in Order

Roy is trapped in a time loop because Colonel Ventor placed him inside the Osiris Spindle, a quantum device that can rewrite history. Jemma secretly placed Roy in the Spindle to stop Ventor's evil plans, but the device malfunctioned, causing Roy to relive the same day over and over. Each cycle starts at 7:00 AM and ends when Roy is killed at 12:47 PM.

Foreshadowing: The film hints at this early when Roy finds a birthday gift from Jemma containing a hidden message about Osiris, suggesting she orchestrated his placement in the loop.

The Osiris Spindle is a revolutionary quantum device created by Jemma at Dynow Labs. It has the power to rewrite history by folding time and space. Ventor intended to use it to become the world's tyrant, but if activated incorrectly, it would trigger an apocalyptic event that destroys the world.

Roy is targeted because Colonel Ventor ordered his elimination after discovering Roy at Dynow Labs near the classified Osiris Spindle project. Ventor viewed Roy as a loose end who might uncover his plans. However, the true target was actually Roy's son Joe, not Roy himself, the assassins were using Roy's location to find the boy.

Foreshadowing: Early in the film, Roy notices assassins in his apartment and a helicopter gunman, but the reason for their focus on Joe isn't revealed until the climax.

Roy figures out he's being tracked through a dental device after multiple loops of trial and error. He discovers that Alice, a dental hygienist he went on a date with, planted a tiny tracking chip in his mouth. This device allowed Ventor's assassins to locate Roy each day, which is how they always find him no matter where he hides.

Jemma was murdered by Colonel Ventor at Dynow Labs after a heated argument. Ventor initially told Roy she died in a lab accident, but he later confessed to killing her personally. Roy eventually discovers she was killed just 14 minutes after each loop begins, which allows him to pinpoint the exact moment to rescue her.

Foreshadowing: When Roy speaks to Ventor in an early loop, Ventor reveals Jemma died the day before, hinting at the truth before the official revelation.

The assassins were targeting Joe because Ventor planned to use the boy as a test subject for the Osiris Spindle. Joe's genetic code was apparently needed to activate the device properly. This is why, despite Roy defeating all the assassins in one loop, the apocalyptic outcome still occurred, Roy arrived too late to save Joe from the Spindle's detonation.

Roy rescues Jemma by realizing she called Joe earlier than he initially thought, suggesting she was still alive. He calculates that she dies exactly 14 minutes after waking in each loop at Dynow Labs. Using this timing, Roy commandeers a helicopter, eliminates the waiting assassins, and confronts Ventor before he can kill Jemma.

Jemma's birthday gift contained a hidden message about Osiris, the Egyptian god of the afterlife. This clue helped Roy understand that Jemma had deliberately placed him inside the Spindle to stop Ventor. The reference to Osiris symbolized the cycle of death and rebirth that Roy was experiencing, and that Jemma had engineered his entry into the loop as part of her plan.

Ventor killed Jemma because she refused to help him use the Osiris Spindle for his plan to become a global tyrant. Jemma created the Spindle but refused to activate it for Ventor's evil purposes, leading to a heated argument where Ventor murdered her. He then covered up her death by claiming it was a lab accident.

When Roy enters the Spindle, he faces a choice: either wake up to relive the day again or potentially vanish entirely. After saving Jemma and sharing an emotional goodbye, Roy steps into the unknown of the Spindle. The ending is ambiguous, he may finally break free from the loop, or he may cease to exist entirely. The international version leaves his fate deliberately unresolved.

Foreshadowing: The entire film builds toward this choice, as Roy transforms from confused survivor to someone willing to sacrifice himself for his family and the world.

Roy hones his sword-fighting skills by taking lessons from Dai Feng, played by Michelle Yeoh. Through repeated loops, he practices intensively and becomes increasingly skilled. This training proves crucial during his final confrontation with Ventor at Dynow Labs, where sword combat plays a key role in defeating the villain's forces.

Roy dies at 12:47 PM because that's when the assassins' final coordinated attack succeeds. By this point in each loop, Roy has exhausted his备 (preparedness) and resources, making him vulnerable. The specific time marks the climax of the daily assassination attempt that sends him back to 7:00 AM to begin the cycle again.

Alice is a dental hygienist who goes on a date with Roy the night before the time loop begins. She was recruited by Ventor's team to plant a tiny dental tracking device in Roy's mouth. This allows the assassins to track his location throughout each day. Roy doesn't discover this connection until several loops into his ordeal.

Joe reveals Roy is his father during a loop at Underground Atlanta. While Roy is protecting Joe from assassins, Joe is mortally wounded. In his final moments, Joe whispers to Roy that he is indeed his father. This emotional moment drives Roy to continue fighting to save his son in subsequent loops.
