Comeback revolves arround Tomáš Pacovský (Tomáš Matonoha), owner of a music store named U Dvou Akordů (Two Accords'), and his family. His brother Ozzák (Martin Dejdar) (the name 'Ozzák' is an allusion to an Ozzy Osbourne fan) is an alcoholic who loves heavy metal music. The majority of jokes and gags are based on his alcoholism and his absolute belief in metal music. Ozzák claims that music which isn't related (more or less) to metal is trash, and not worth of selling, only metal is the true quality, and it should be given away for free. Tomáš has a beautiful, teenage daughter Iva (Kristýna Leichtová) who is (only seemingly) the only normal member of the family. Other characters include Simona (Simona Babčáková), slightly odd, middle-aged woman with a very hooked nose, who owns a pub named "U Jezevce" in the first season, where Ozzák spends most of his free time and money.
