Helena groeit op met haar vader en moeder in de moerassen van Michigan, ver afgezonderd van de rest van de wereld. Haar excentrieke vader, die Helena’s moeder ontvoerde en bekend staat als ‘The Marsh King’, leert Helena jagen en overleven in de wildernis, totdat haar moeder een manier vindt om met haar te vluchten en haar vader wordt opgepakt. Twintig jaar later heeft Helena haar verleden achter zich gelaten en een gezin opgebouwd. Maar wanneer haar vader uit de gevangenis ontsnapt, komt haar verleden aan het licht en heeft The Marsh King het op haar en haar dochtertje gemunt. Ze weet meteen dat er maar één persoon is die hem kan opsporen: Helena zelf.
Nee, helaas is The Marsh King's Daughter nog niet beschikbaar op Netflix in Nederland.
