Parents need to know that 2 Hearts is a romantic mystery based on real events that finds a positive outcome from tragedy. Adapted loosely from Eric Gregory's nonfiction book All My Tomorrows, it follows the evolution of two romances with themes related to illness, death, grief, and hope. The first, in the 1970s, involves wealthy Cuban-born rum executive Jorge (Adan Canto) and flight attendant Leslie (Radha Mitchell). Drinking and cigar smoking crop up regularly in their storyline, and they're shown in bed together having an implied after-sex conversation (sensitive body parts are covered by a sheet). A couple of curse words are said, including "f--k" and "goddammit." The other relationship is between modern-day college students Chris and Sam (Jacob Elordi and Tiera Skovbye), who come together through volunteer work. The movie portrays relationships and characters in a way that reinforces gender stereotypes: It's love at first sight for the men, who then pursue the women relentlessly. Jorge aggressively woos his future wife with riches and luxury, flying all over the world to surprise her, behavior that some may see as stalkerish rather than affectionate.
