Malevolent, unearthly creatures called shetani, which inhabit another dimension the Maasai know as the “Out Of” (because all things, such as humans, animals and plants, originally came "out of" it), are finding their way into the world.

If not prevented, the barriers between the two dimensions will be breached and uncountable hordes of shetani will overrun the world, destroying all life.

He encounters Joshua Oak, a disenchanted FBI agent, and Merry Sharrow, a shy and unfulfilled call centre worker.

Eventually, Olkeloki takes Merry and Oak into the Out Of, where, with their help, he performs a ritual which seals the breach between dimensions, sacrificing his own supernatural powers in the process.

All three return to this world, where the shetani’s tricks have ended and the diplomatic crisis is receding, and Oak and Merry realize they have found what they have been looking for in each other.
