Oscar and Teo (13 and 11 years old) are two brothers, very different from each other, who will have to face the loss of their mother, a scientist obsessed with wormholes.

Brothers Teo and Óscar become separated when Teo disappears down a mysterious wormhole in 1989. When he reappears exactly the same, 33 years later, he must work together with his now-older brother to find the right wormhole to send him back and find their mother. A terrific sci-fi romp through time.
