Naxum Space, the world's largest space agency, is on the brink of winning the space race to control space-time. However, a brilliant researcher with Down syndrome manages to be the first to achieve this significant milestone. Sirbino Probetus, son of a missing science legend, oversees the Space-Time Incursions department, a secret program started decades ago. The boy scrutinizes his own past, where he revives certain thoughts, and a dawning suspicion that he will not be able to let go of. After 28 years, the facts of his disappearance remain unclear, and now new clues are emerging about his investigations and about what happened. After a series of adventures visiting past eras, he receives an anonymous SOS call, a call that will forever change his life as well as the physical laws of the multiverse.
