Secret of the Wings (originally titled as Tinker Bell and the Mysterious Winter Woods or alternatively Tinker Bell and the Secret of the Wings) is a 2012 American animated fantasy film, and the fourth installment in the Disney Fairies franchise, produced by Disneytoon Studios.

It revolves around Tinker Bell, a fairy character created by J. M. Barrie in his 1904 play, Peter Pan, or The Boy Who Wouldn't Grow Up, and featured in subsequent adaptations, especially in Disney's animated works, and how she ventures to the Winter Woods and meets her twin sister, Periwinkle, who is a frost fairy.

[4][5] Starring the voices of Mae Whitman, Lucy Liu, Megan Hilty, Raven-Symoné and Angela Bartys, it also features new cast members who include Matt Lanter, Timothy Dalton, Lucy Hale and Debby Ryan, while Anjelica Huston narrates.

However, fairies from the warmer seasons are forbidden from crossing the border to the Woods as the cold can damage their wings, a law supposedly instated by Lord Milori.

At Peri's home, Tink builds a fire which eventually causes the floor to melt and crumble beneath them.

With the machine keeping her cool, Peri crosses over and Tink introduces her to her friends, showing her the warm side of Pixie Hollow.

Tink and her friends rush her to the border and meet Lord Milori, who takes Peri back to the Woods.

Tink and Periwinkle are told, by Queen Clarion and Lord Milori respectively, the story of two fairies who fell in love, one from the warm seasons, the other from the Woods.

Receiving news of an emergency, Tink and Clarion return to the border and find that the snow-maker has been collecting ice from the stream, generating snow and causing a blizzard.

As the freeze approaches, Lord Milori warns the warm fairies to take cover, including Clarion whom he gives his cape, revealing one of his wings is broken.
