Red Sun Plot Explained: Your Questions Answered

The questions people ask most about Red Sun (1971): what happens in the confusing scenes, why the characters do what they do, the twists, hidden details and what the ending means. Each answer contains spoilers.

Q2

Why is Kuroda so determined to recover the ceremonial sword?

Kuroda explains that returning the sword is essential to preserving samurai culture, which he feels is fraying. The tachi is not just valuable, it represents his ancestors and the honor code he lives by. If he fails to retrieve it, he must commit seppuku anyway, so pursuing Gauche becomes both a matter of personal honor and cultural duty.

Q3

Why does Gauche kill his own gang members after burying the loot?

Gauche murders his remaining men to maintain sole control over the buried treasure. He pays off some who leave, but those who stay loyal become a threat to his exclusive claim on the money. By eliminating them, he ensures no one else can access the stash, making the hidden loot the central motive driving the rest of his actions.

Q5

Why do Link and Kuroda use Christina to get to Gauche?

They track Christina to a San Lucas brothel and trap her inside a room to use her as leverage. Since Christina has some connection to Gauche, they understand she is his emotional weakness. By holding her, they can force Gauche to come to them rather than continuing to chase him across difficult terrain.

Q6

Why do the Comanches attack at the abandoned mission?

The Comanche attack is triggered when Christina escapes from Link and Kuroda and runs into Comanche territory. One Comanche tries to assault her and is killed. The Comanche leader then binds her neck with wet rawhide that tightens as the sun dries it, and the tribe pursues the group at the mission. Their attack forces the rivals to temporarily unite against a common enemy.

Q7

Why does Kuroda hesitate to kill Gauche during the final duel?

Kuroda hesitates because Link had earlier pleaded with him to let Link be the one to kill Gauche. When the moment comes, Kuroda honors Link's request rather than acting on his own vengeance. This hesitation costs him, Gauche shoots Kuroda while he lowers his weapon, but it demonstrates Kuroda's respect for his reluctant partner.

Q9

What would happen if Link and Kuroda missed the one-week deadline?

The ambassador imposes a strict one-week deadline to recover the sword. If they fail, both Kuroda and the ambassador must commit seppuku, the ritual suicide reserved for samurai who have lost honor. This creates the urgent time pressure that drives the entire chase narrative, giving both characters life-or-death motivation to pursue Gauche.

Q10

Why do Link and Kuroda fight together against the Comanches?

The Comanche attack at the abandoned mission forces the natural enemies to temporarily ally. Gauche and his men are already ambushing Link and Kuroda when the Comanches strike, creating a three-way battle. Facing a common enemy with superior numbers, the rivals must combine forces to survive, fighting inside the burning mission and later in the cane fields together.
