De befaamde dodelijke Leprechaun heeft zijn zinnen gezet op een buitenaardse prinses Hij wil met haar trouwen, zodat hij koning kan worden. Een groep Amerikaanse mariniers weet hem te stoppen en de prinses mee te nemen naar hun ruimteschip, waar ze wordt verzorgd door een gestoorde wetenschapper. De Leprechaun is hier alles behalve gelukkig mee en wil de prinses koste wat kost terugkrijgen.
Nee, helaas is Leprechaun 4: In Space nog niet beschikbaar op Netflix in Nederland.
