The 1966 construction of Alexander Calder's 'La Grande Voile' (The Big Sail), a monumental sculpture installed in McDermott Court at MIT in Cambridge.

The film begins with a sun materializing out of the emptiness of space. In the first of three sequences we see various images from nature against music: the sky, trees, leaves, a bird, water, sand, a beach. A little boy wanders along the beach observing the natural world around him. He walks and presently comes to a house and peers inside. The second sequence has no music. The narrator speaks of sculptor Alexander Calder and his work, as we see Calder in his workshop, cutting and creating unusual shapes, and seeing the resultant artworks. The last sequence has music as we view images of Calder's work. However, now they are intercut with images from nature so that we understand that Calder's inspiration is the natural world around him. The film ends as it began, with an image of the sun, now fading into the sky.

In the remote village of Calder's End stands an old windmill, a repository of dark secrets. Nicholas Grimshaw has returned to this haunted place, his childhood home, intent on breaking a generations old family curse. Grimshaw's journey takes him deep below the decaying mill,into mysterious, forgotten catacombs, where upon he confronts the very source of the evil that has corrupted his family. The Mill at Calder's End is a gothic tale inspired by the tales of Edgar Allan Poe, H.P. Lovecraft, and M.R. James and is told with the use of 36 inch tall bunraku rod puppets operated by puppeteers dressed in black.
