Passengers on a regular commercial flight, a few hours after embarking, are involved in an astonishing, nonviolent abduction by beings from another galaxy, holders of an overdeveloped civilization.
Once in that distant and infinite space, where everything is completely strange, they found strange forms of life.
At the edge of their psychic resistance, they were returned to Earth. Upon their return, they came across a temporal space they would never have imagined they could witness.
