Hoe weet je dat je de ware gevonden hebt? Daar draait het om in dit verhaal. We volgen Lisa, een professionele softbalspeelster, Manny een honkbalspeler uit de Majorleague en George, een directeur die op het punt staat alles te verliezen, en hun driehoeksverhouding. Charles de vader van George staat klaar met goedbedoelde adviezen.
Nee, helaas is How Do You Know nog niet beschikbaar op Netflix in Nederland.
