Het waargebeurde verhaal over Martha Beck en haar handlanger Raymond Fernandez die in de jaren '40 zeventien vrouwen beroofden en vermoordden, die ze hadden gelokt door liefdes-advertenties in de krant te zetten. Hierdoor werden zij al snel de 'Lonely Hearts killers' genoemd.
Nee, helaas is Lonely Hearts nog niet beschikbaar op Netflix in Nederland.
