Sinbad: Legend of the Seven Seas

Sinbad was framed for the theft because Eris, the Goddess of Discord, disguised herself as Sinbad to infiltrate the tower housing the Book of Peace. She successfully stole the tome and escaped, leaving Sinbad's belongings as false evidence that pointed to his guilt.

Earlier in the film, Eris had attempted to tempt Sinbad with riches in exchange for the Book, establishing her interest in framing him.

Proteus believed in Sinbad's innocence despite the circumstantial evidence. Their childhood friendship gave Proteus confidence that Sinbad was incapable of such a betrayal. By offering to take Sinbad's death sentence, Proteus bought him crucial time to recover the Book and clear his name.

Sinbad and Proteus were childhood friends who fought together against Cetus, demonstrating their bond.

Eris needed a way to enter the tower undetected and steal the Book without raising immediate suspicion. By taking Sinbad's appearance, she could access the guarded location and ensure the theft would be blamed on Sinbad, advancing her scheme to create chaos while remaining in the shadows.

Eris had directly approached Sinbad earlier, offering him a deal for the Book, showing her cunning nature.

Eris's true scheme went beyond simply stealing the Book of Peace. She intended to secure the Book while simultaneously plotting to bring down Proteus, the heir to Syracuse. By framing Sinbad and having Proteus executed for a crime he didn't commit, Eris aimed to plunge the Twelve Cities into ultimate chaos.

As the Goddess of Discord, Eris's ultimate goal was always to cause chaos among the Twelve Cities.

Marina joined Sinbad for several reasons: she wanted to prove Sinbad's innocence to save Proteus, she possessed valuable navigation skills as the ship's pilot, and she had jewels to pay Sinbad for passage. Additionally, her growing feelings for Sinbad motivated her to help him succeed.

During the feast in Syracuse, Sinbad's reaction to Marina revealed his secret love for her, establishing their emotional connection.

Sinbad and Proteus fought together against the sea monster Cetus, which Eris had unleashed to attack their ships. Working as a team, they managed to defeat the beast, though the victory came with consequences that left Sinbad adrift at sea.

Eris released Cetus specifically to disrupt the Book's transport and create opportunities for her scheme.

When Eris offered Sinbad untold riches in exchange for stealing the Book, he initially declined because his crew laughed at the ridiculous proposition and because Sinbad still valued his friendship with Proteus enough to refuse such a treacherous act at that moment.

This moment established Sinbad's initial moral standing before circumstances led him into danger.

At Tartarus, Eris revealed her true intentions to Sinbad: not just stealing the Book, but also bringing down Proteus. Sinbad faced a desperate choice, escape with Marina or try to stop Eris. His decision to fight Eris resulted in both him and Marina being tossed out of Tartarus, leaving Proteus's fate uncertain.

Eris had been manipulating events throughout the journey, leading to this final confrontation.

After being expelled from Tartarus, Sinbad raced back to Syracuse and arrived just in time to save Proteus from execution. His heroic actions restored peace to the city and cleared his name, though the adventure came at a personal cost.

The stakes were highest in Tartarus, where Sinbad's choice directly determined whether Proteus would live or die.

Sinbad undertook the dangerous quest primarily to rescue Proteus, who had shown loyalty by offering to die in his place. Despite being a notorious pirate, Sinbad's code of honor and his friendship with Proteus drove him to risk his life and face impossible odds to retrieve the Book.

Proteus's sacrifice in offering to take Sinbad's punishment established the depth of their friendship.
