A troubled man seeking spiritual renewal in the wilderness experiences a wholly unexpected rebirth - as a walking monolith, half a ton of animate stone able to perform astonishing feats of strength and endurance but forever denied many of life's fundamental pleasures. As Concrete, Ronald Lithgow becomes an overnight celebrity and the focus of dark government operatives desperate to keep the secret of his metamorphosis from the public. Concrete must struggle with the loss of his humanity while discovering, perhaps for the first time, what it truly means to be human.
