Rimsko Carstvo, potkraj 2. stoljeća. Car Marko Aurelije pokušava spriječiti prodor barbarskih plemena na sjevernim granicama u čemu mu presudno pomaže hrabri posinak i vojskovođa Maximus. Nakon pobjede u krvavom boju, ostarjeli vladar upravo u Maximusu vidi svog nasljednika, iako ga u Rimu čeka njegov rođeni sin Komod. Doznavši da će ostati bez carske titule, beskrupulozni Komod odluči ubrzati stupanje na prijestolje, te nakon očeve smrti zapovjedi ubojstvo Maximusa i njegove obitelji. Za razliku od obitelji Maximus izbjegne smrt, ali ne i odlazak u roblje pri čemu ga kupuje Proximo koji trenira najbolje gladijatore u Carstvu. Postavši Proximov najslavniji borac u areni, Maximus se zavjetuje da će usred Rima osvetiti smrt svoje neprežaljene obitelji.
