When a young boy's beloved plum tree falls in a storm, he feels like he's lost both a friend and a connection to his old home.

A young boy, recently arrived from Korea, finds a glorious plum tree in his new backyard. It reminds him of a tree his family had back home, and he names it Plumee for the deep purple plums on its branches. Whenever the boy is homesick, he knows he can take shelter in Plumee's tall branches.

And when a storm brings the old tree down, he and his friends have all kinds of adventures on its branches, as it becomes a dragon, a treehouse, and a ship in their imaginations. But soon it's time to say goodbye when the remains of the tree are taken away. Before long, a new plum tree is planted, new blossoms bloom, and a new friendship takes root.
