Roman Hlava grew up with his diplomat parents in Latin America where he had been home-schooled by his over doting mother. The over indulgence of affection and praise has given the boy an over confidence. This is quickly squashed by his new peers when the family returns to the Czech Republic. This leads to neurotic tics and the nickname Mrkácek the 'Blinker.' A stay at a children's camp provides new friends, acceptance, an appreciation of nature, a new outlook on life, and loss of the tics.

Blinker, so named because he blinks whenever he has a bright idea for a new invention, is the son of an eccentric Professor who is developing a top secret Pulsar Crystal X. Blinker's inventions help him to be a successful goalkeeper and to keep an eye on The Masons gang - and some real crooks.
