Percy Jackson je kot ponavadi vedno v težavah.Režiser prvih dveh filmov o Harryju Potterju predstavlja zgodbo 12-letnega Percyja, ki nekega dne odkrije, da je potomec starogrških bogov. Toda božanstva na Olimpu niso zadovoljna, saj je nekdo ukradel Zevsovo strelo, glavni osumljenec pa je nič hudega sluteči Percy. Da bi odkril, kdo stoji za tatvino, preprečil vojno med bogovi in našel pogrešano mamo, se Percy z zvestima prijateljema poda na nepozabno pustolovščino, polno nevarnosti in vratolomnih doživetij.
