  We study a scalar field theory in a flat five-dimensional setup, where a
scalar field lives in a bulk with a Dirichlet boundary condition, and give an
implementation of this setup to the Froggatt- Nielsen (FN) mechanism. It is
shown that all couplings of physical field of the scalar with the all brane
localized standard model particles are vanishing while realizing the usual FN
mechanism. This setup gives the scalar a role as an only Gravitationally
Interacting Massive Particle (GIMP), which is a candidate for dark matter.
