Buckminster Fuller spent decades chasing one idea: that shelter could be redesigned from first principles rather than inherited from centuries of building tradition. This film traces how that pursuit led him to the geodesic dome, a structure built from interlocking triangles that distributes stress evenly across its surface, letting it enclose enormous volumes with a fraction of the material a conventional building would need. Archival photographs and footage follow Fuller's dome from early experimental prototypes through its adoption by the US military, corporations, and world's fairs, including the famous Montreal Expo 67 dome. The film lays out Fuller's broader philosophy of doing more with less, treating the dome as one expression of a lifelong project to apply engineering logic to human comfort and efficiency. It is a compact account of an eccentric inventor's most visible legacy, useful both as design history and as a portrait of a mind that treated housing as a problem to be solved rather than a tradition to be followed.
