Eight spaceships disappear and radio contact to the enormous space station "Margot" is broken off. Professor Maria Scholl and the high council decree a flight ban for all other spaceships. Nevertheless one ship succeeds in leaving earth. The cause of all these strange events is the mysterious signals in Morse code coming to earth from the constellation Cygnus. Deciphered, they say the word "Eolomea," which seems to refer to a planet. With Captain Daniel Lagny, an unmotivated eccentric, Maria Scholl undertakes the risky journey to the space station "Margot" to uncover the secret, only to discover that a secretly planned expedition of stolen spaceships is leaving for Eolomea against the will of the government.
