Exiled to a summer camp called "Hope" run by a one-eyed fellow named Falconetti, this is a strict re-education center for rascally teenagers, which dashes any hope for fun our two heroes might have had...until they form a Children's Resistance called the Marble Gang.
We see:
- Javier Gutiérrez is Falconetti, he enforces a stern set of rules which forbid any fun; he has a heavy hand, an eyepatch and all things dreary.
- Raúl Rivas is Zipi, he's the smart one, and he gets a crush on Matilde.
- Daniel Cerezo is Zape, he's the devilish one, and Matilde gets a crush on HIM!
- Claudia Vega is Matilde, Falconetti's niece. She doesn't like her uncle very much, but she really doesn't want to go home, either ...but she does like bad boys....
- Fran Garcia is Filo, the standard pudgy guy who has trouble keeping up with the other four as they flee through those cobwebby tunnels. (Did I mention that this film has very broad stereotypes? They fit like a pair of comfortable old shoes.)
- Marcos Ruiz is Micro, the nerd. No kids' movie would be complete without a skinny boy in thick glasses, wearing braces on his teeth and with a history of being bullied.
