The Trailer for Apple TV+'s Fingernails' Mixes Love & Science

Is it possible to measure love? To know for sure that you truly loved someone? And that they loved you back? What if you could know, instantly, whether or not your partner was your forever? That's the premise behind the upcoming Apple TV+ feature film Fingernails, a sci-fi romantic drama set in a future where scientists have developed a controversial test purported to allow couples to be able to determine whether they're truly in love.

All it takes is a single (you guessed it!) fingernail from each partner, and they're able to know instantly whether a given relationship is built to last — or doomed to fail. The story follows Anna (Jessie Buckley), an unemployed teacher whose long-term relationship with boyfriend Ryan (Jeremy Allen White) was confirmed as a genuine love match by just such a test several years ago. But when she gets a job at the same institute that administers the tests, she finds she's irresistibly drawn to a handsome coworker in spite of herself. (And in spite of her supposedly loving and happy relationship with Ryan.)

As a result, Anna begins to question whether it's possible to be in love with two people at once — something the Love Institute insists isn't possible. But can something as impossible as love can ever be quantified or explained by science?
