Eye of the Moon Plan

The is Madara Uchiha's ultimate plan for world domination, which seems to involve using Sasuke Uchiha to synchronize with the Demonic Statue of the Outer Path, of which holds seven of the nine tailed beasts gathered by Akatsuki. Madara notes that after Sasuke has failed to capture Killer Bee and the Eight-Tailed Giant Ox, he has been cautious for too long, and that it is time to emerge from the shadows and commence with this plan.

After Madara revealed this plan to four of the five Kage at the Land of Iron, they responded in refusing to hand over the last two Jinchūriki, Naruto Uzumaki and Killer Bee, and formed a Shinobi Alliance to prevent the Moon's Eye Plan from succeeding.

The Plan
Madara's plan is to gather all the Tailed-Beasts in order to fuse them back into their original form, the Ten-Tailed Beast. He will then become jinchūriki to the Ten-Tailed Beast giving him immense power and the ability to project his Mangekyo Sharingan on to the moon. He intends to use the moon, the prison of the Ten-Tail's body, to cover the world in an "Infinite Tsukuyomi", thereby letting him control every living being, creating a world in which no war or crime occurred.

Part of his plan was to have Zetsu attract the attention of the five Kage and lure them to fight against Sasuke. In doing so, Madara hoped that the five would be weakened enough for him to take them as hostages to negotiate the capture of the Hachibi and the Kyubi. This, however, ended in failure, due to Sasuke exhausting himself to the point of death in his fight against Ē, the Raikage.
