Michael Portillo begins a new journey from Minnesota's Twin Cities in the north of the US to Memphis, Tennessee, in the Deep South.

In this leg, Michael discovers how Minneapolis, part of one metropolitan area with its immediate neighbour, St Paul, harnessed the power of the mighty Mississippi to become a great industrial centre. It is also the artificial limb capital of the world.

In St Paul, meanwhile, Michael visits the birthplace of F Scott Fitzgerald and meets a jazz age trumpeter and Fitzgerald fan who introduces him to the Jay Gatsby lifestyle.
