It's the early 1980s and the Sympathizer arrives in Paris. As a refugee, he and his blood brother Bon try to escape their turbulent pasts by turning their hands to capitalism in one of its purest forms: drug dealing. No longer in physical danger, the Sympathizer is both charmed and disturbed by Paris. Falling in with left-wing intellectuals and politicians at dinner parties held by his French Vietnamese "aunt", he finds customers for his merchandise as well as stimulation for his mind. But this new life he's living has unforeseen dangers of oppression, addiction and the seemingly unresolvable paradox of reuniting his two closest friends, men whose world views stand them poles apart.
