They manage to arrive in the proverbial nick of time to thwart the assassination, forcing John and the Sheriff to resolve the matter in close combat.
After Spike discovers the location for John's ambush, Tom, Jerry, Robin and his men come to the rescue. Spike, Tyke and Droopy enter the castle unchallenged and, while looking for their comrades, end up freeing Marian.
Meanwhile, John, the Sheriff and their henchmen ride off to set their trap for Richard.
As a result, Tom revokes his loyalty to John, frees Jerry and teams up with him in order to free Robin and the Merry Men from prison. John and the Sheriff begin to hatch a scheme to ambush and kill Richard before he can set foot on British soil, and also decide to execute Marian for her "treachery". Tom finally captures Jerry, but is rudely dismissed by John and the Sheriff, who have just learned to their dismay that King Richard, John's brother and the rightful King of England, is returning from the Crusades much earlier than anticipated. As they fight in Marian's room, they are accidentally evicted by the Sheriff, who then discovers that Marian is Robin's informer and places her under arrest. Jerry, the only Merry Man (besides Spike, Tyke and Friar Droopy) left at large, penetrates the castle in order to free his companions, but is discovered and engaged by Tom. When Jerry is chased by Tom while delivering a ring of love from Robin to Marian, he accidentally helps him win the contest the Sheriff unmasks him and Robin and his men end up captured. Robin cannot resist the temptation and decides to participate, despite the misgivings of his men. The Sheriff devises a plan to capture Robin at a staged archery tournament, with a kiss from Marian as an additional enticement. However, Marian is being kept company by Tom and upon spotting Jerry approaching the castle, he attempts to thwart the mouse but fails. The very same night, Robin asks Jerry to deliver a love poem to Maid Marian (played by Red Hot), his secret contact and love interest. When John and the Sheriff discuss this latest fiasco, the Sheriff deduces that Robin uses Jerry to ferry information to and from a spy inside the castle, and tasks Tom to catch Jerry in order to flush out the traitor. However, thanks to Jerry's advance warning, Robin has summoned his Merry Men to the scene, turning the enemies into ambushes and successfully seizing the gold transport. Robin Hood and his companion Jerry attempt to ambush a tax money transport going through Sherwood Forest The transport is a setup for a trap by the Sheriff of Nottingham, Prince John's right-hand man who is accompanied by his henchcat Tom.
