Small town smack bang in the American Midwest. Suzanna aged 23 changes gender and becomes a boy: Coby.

Her transformation deeply disrupts the lives of all who love her. Ultimately, Coby’s chrysalis becomes morphs into the transformation of a whole family compelled to modify their own perspectives.

Not only a physical metamorphosis is at stake here but also a spiritual one that eventually takes place under the director’s bright, unusual eye.

“Changing has consequences. Not changing also has consequences“.
