Gui is back! Who is Gui? He's a child who dreams. He goes into his room after a day at school and embarks on his imaginary world. In that room anything is possible. Windows break, howls, sirens and even voices from beyond are heard. The phone rings and rings and rings. It's time to solve another case. As Batman has Robin, Phineas has Ferb, Detective Gui has Inspector Marcelo. And the two of them are ready for another great adventure. — Teatro Sá da Bandeira
