Cary Grant operates some planes flying mail over jungle passes in South America. The problems start when Jean Arthur arrives on a boat and then his ex-girl friend (Rita Hayworth) arrives to complicate things further. This is a good film with plenty of atmosphere and good acting highlighting the strained relationships. This was Rita Hayworth's first major film. Lucas and Speilberg have said this was a precursor to the Indiana Jones films with its action figure and sequences.
