Industrialist Stefan Denaerde was at anchor in his sailboat accompanied by his son when their radar began to malfunction. Later on he starts to sail towards Burgsluis. At this point they see what they described as "a blue sun" descending from the sky emitting a strident noise. Denaerde then sees a figure that appears to be injured floating in the water. He jumps in the water and retrieves the body. At this point the "blue sun" descends over them and Denaerde can see that it is a metallic saucer shaped craft a door opens and a staircase is lowered down to the water, a figure is seen standing at the door. Denaerde is suddenly absorbed into the saucer and is confronted by several humanoids about 1.40 meters in height, equipped with astronaut-like uniforms adorned with multiple ornaments. They have a very high face, pointed ears and speak in a mechanical English voice. They thank Denaerde for helping their injured comrade in the water and tell him that they are from a distant planet, which they call Iarga, about 10 light years away. People live there in cylinder-like structures because of the rampant overpopulation. They practice a sort of Communism and advice Denaerde that private property does not exist. Their only goal is "an omni spiritual creativity".
