What is the new legend of Zelda game about?

Answer 1

Assuming you are referring to Skyward Sword:

Link was and raised in Skyloft, a land floating above the clouds and above the land of Hyrule. An adept bird rider (the trailer shows him riding a large bird/pterodactyl-esque creature), Link wins a contest held during a festival celebration, and will receive a prize from Princess Zelda. They embark on a flight trip; however, a tornado suddenly appears and takes Zelda. Link must rescue her, and to aid him on his quest, the villagers give him his trademark green clothing and the titular Skyward Sword, which is occupied by a spirit named Phi who accompanies Link on his quest. Link travels to Hyrule, and ventures to the Sky Temple where Zelda is supposedly kept prisoner. Here he meets the Demon Lord Ghiramim, ruler of the chaotic surface world. His tribe also seeks Zelda, for reasons yet unknown. Ghirahim escapes after haven been defeated, and Link resumes his quest to rescue the princess before she is found by Ghirahim's forces.
