Suéltate el pelo (1988)

Pop group "Hombres G" is at the height of its popularity. They are very successful, and the harassment from fans and admirers is overwhelming. Frontman David, through a fan-letter, meets Sonia, a fan who is totally crazy about him, but she rejects her for being a minor. Shortly after, a strange character blackmails him with some photos; then everything gets complicated to the point that David ends up in prison. But his friends and band co-members are not going to sit idly by.
