Jiu Jitsu (2020) Timeline Explained – Every Event in Order

Jake suffers from amnesia because he is a veteran of the previous Jiu Jitsu battle against the alien invaders six years earlier. Wylie reveals that Jake fought alongside the martial artists in that earlier conflict, but the traumatic experience and likely a defeat caused him to lose his memories. The truth serum at the military base fails because his mind voluntarily suppressed the painful past.

Foreshadowing: The mysterious western man who rescues Jake in the opening jungle scene appears to know him, hinting at their shared history.

Jake's jiu-jitsu skills are embedded in his muscle memory from years of training before his amnesia. Even though he cannot consciously recall his past, his body retains the martial arts expertise he developed as a defender in the previous alien invasion. Keung recognizes Jake through a special handclasp, confirming their shared history in the order.

Foreshadowing: During the escape from the military base, Jake instinctively displays advanced fighting techniques that surprise even himself.

The aliens use a mystical portal located within the Jiu Jitsu temple to cross into Earth's realm. This portal has been used for millennia, opening every six years when a comet appears. The ancient order of Jiu Jitsu fighters was founded specifically to defend humanity at these portal entry points, preventing the aliens from conquering Earth.

Foreshadowing: Myra mentions villagers speaking of a comet appearing every six years and a temple portal before Jake's amnesia is even addressed.

Wylie is Jake Barnes' father, a revelation he shares with shame after surviving the battle with Brax. Wylie explains he was an escapee from the previous invasion who failed in his duties, leading him to abandon his family and hide in isolation. This confession comes during a moment of reconciliation as Jake prepares for his final confrontation with the alien leader.

Foreshadowing: Wylie shows an unusual personal interest in Jake's survival and training from the moment they meet in his cave.

Brax is vulnerable to fire, a weakness Jake discovers during an earlier confrontation and exploits in the final battle. After learning of this vulnerability, Jake arms himself with a grenade and uses Brax's weakness to drive the explosive directly into the alien's core, then shoves him into the portal as it collapses.

Foreshadowing: Earlier combat scenes show Brax recoiling from fire-based attacks, though this detail is easy to miss amid the action.

The invasions occur every six years due to a celestial event, a comet that aligns with Earth and weakens the barrier between realms. This comet allows the portal to open, enabling the alien race to cross into Earth's dimension. The ancient Jiu Jitsu order was established precisely around this cycle, training fighters to defend humanity during each invasion window.

Foreshadowing: Villagers near the military base speak of a comet appearing every six years, which Myra tries to connect to the invasion reports.

• comet invasion

Keung recognizes Jake because they fought together in the previous Jiu Jitsu battle against the alien invaders six years ago. The two share a special handclasp greeting unique to the order's members. Despite Jake's amnesia, Keung's unshakable trust in him stems from their shared history as Earth defenders, and he breaches the military base specifically to rescue his former comrade.

Foreshadowing: The mysterious western man who saves Jake in the opening scene also appears to know him, foreshadowing Jake's forgotten past.

Wylie sacrifices himself to atone for his past failures and to buy Jake time to reach the portal for the final confrontation. Haunted by his cowardice during the previous invasion, Wylie challenges Brax in single combat knowing he likely cannot win. His sacrifice gives Jake the opportunity to recover and prepare for the decisive battle, transforming his shame into redemption.

Foreshadowing: Wylie explicitly states his desire to make amends for leaving the fight early in the previous invasion.

Carmen survives Brax's assault on the temple, making her one of the few Jiu Jitters fighters left alive. She was Jake's former lover before his amnesia and becomes a key ally in the final battle. Her survival is significant because she provides emotional support and fights alongside Jake during the critical moments leading to his confrontation with Brax.

Foreshadowing: The fighters mention Carmen as Jake's former lover when they arrive at the temple, suggesting their past relationship will matter.

Jake defeats Brax by exploiting the alien's fire vulnerability in the final confrontation at the portal. After a grueling battle, Jake shoves a grenade into Brax's core and forces the alien toward the portal. As Brax is propelled through the gateway, the portal collapses behind him, sealing the invasion and saving Earth.

Foreshadowing: Earlier combat demonstrates that fire-based weapons cause unusual reactions from Brax, setting up this eventual strategy.

Harrigan is a seasoned Jiu Jitsu master who leads a band of fighters defending Earth against the alien invasion. He serves as Jake's mentor throughout the film, guiding him despite his amnesia.

Foreshadowing: Harrigan addresses Jake by name with familiarity when they first reunite, indicating a pre-existing relationship.

Jake does not fully recover all his memories by the film's end, but his amnesia is replaced with a renewed sense of self and purpose. The emotional weight of learning his father's identity and the battle itself helps him reclaim enough of his past to understand his identity as a defender. The ending suggests his memories may gradually return as he continues training.

Foreshadowing: Jake's memories surface in fragments throughout the film, building toward partial recall rather than complete restoration.
