Poet Roger McGough narrates the extraordinary story of how a simple invention - the shipping container - changed the world forever and forced Britain into the modern era of globalisation. With a blend of archive and modern-day filming, the incredible impact of the box is told through the eyes of dockers, seafarers, ship spotters, factory workers and logisticians. From quayside in huge container ports to onboard ships the size of four football pitches, the documentary explains how the shipping container has transformed our communities, economy and coastline.
