Ze heet Celeste, heeft lange benen, blond haar en een superfiguur. Kortom, ze is buitenaards mooi. Geen wonder want Celeste komt van een andere planeet en kreeg van haar boordcomputer het; ' mannenfantasie-vrouwelijk-ideaalbeeld lichaam'. Op aarde moet Celeste de onhandige natuurkundige Dr. Steve Mills een geheim ontfutselen, waarvan het voortbestaan van haar hele ras afhangt. Geen wonder dus dat Celeste gelijk ter zake komt en alle trucs tevoorschijn trekt om Dr. Mills voor zich te winnen.
Nee, helaas is My Stepmother Is an Alien nog niet beschikbaar op Netflix in Nederland.
