Trilogy is an anthology film of three adaptations of Truman Capote short stories: Miriam, Among the Paths to Eden and A Christmas Memory. It was listed to compete at the 1968 Cannes Film Festival, but the festival was cancelled due to the events of May 1968 in France.

As Christmastime approaches in rural, Depression-era Alabama, a young boy and his best friend, an elderly woman distantly related to him, prepare for the impending holiday by gathering ingredients for their annual batch of fruitcakes for "people who've struck our fancy." On Christmas Eve, they talk with great anticipation of the next day, but underneath is the sad, almost unspoken knowledge that the boy is growing up and his cousin is getting older and frailer. Based on Truman Capote's autobiographical short story.
