Follows three young millennials as they form a wholehearted ménage à trois, each of them going through a moment of transition: Fun-loving Marcello from under the thumb of his Italian soap star father, soulful French-Iranian actor Nassim toward a more fulfilling career, and artist Christine through the grief following the death of her grandfather. The trio finds joy together by joining political protests, making art, and falling deeper into their unconventional love, until Marcello must return to Italy.

Set in the near future, Gadget tells the story of Neem, a man jaded by the alienating, technology obsessed world he lives in.
