Tired of their lower status among their peers, the trinity in charge of planet Earth opens communications with megacorporation Vivaxis at the end of the 20th century - an occurrence Valerian and Laureline's allies report to the two ex-agents. But to what end did the Hypsians initiate such a contact? And who is the mysterious Sat who, from the depths of Point Central, also endeavours to meddle with Human affairs?
