Op het platteland van West-Massachusetts brengt de 11-jarige Lacy de zomer van 1991 thuis door, geboeid door haar eigen verbeeldingskracht en de aandacht van haar moeder, Janet. Naarmate de maanden verstrijken, komen drie bezoekers hun baan binnen, allemaal gefascineerd door Janet en haar betoverende karakter. Op haar eenzame momenten bewoont Lacy een innerlijke wereld die zo buitengewoon gedetailleerd is dat deze in de buitenwereld begint door te sijpelen.
Nee, helaas is Janet Planet nog niet beschikbaar op Netflix in Nederland.
