  We construct a conformal scattering theory for Dirac fields in the interior
of a Reissner-Nordstr\"om-like black hole, between the black hole event horizon
and the Cauchy horizon. The main result is a resolution of the characteristic
Cauchy problem for the Dirac equation on the horizons by solving a system of
wave equations and re-interpreting its solution as the components of the
required Dirac solution.
