Isaac is a middle-aged actor who lives with his girlfriend, Ramona, who is blind and works for a pharmaceutical company that requires her to travel frequently.
Isaac leads an acting workshop where he routinely lavishes praise on Alex, his star pupil who is also a working actor, while either denigrating or ignoring Tracy, another one of his students. He is secretly jealous of Alex as his own acting career has devolved into commercial and modeling work for pharmaceutical products.
After overhearing a message from Ramona in which a man can be heard in the background, Isaac has a breakdown. He invites Alex over for dinner, accusing him of using him and then trying to kiss him. Afterward, Ramona returns home from her trip and breaks up with Isaac ending their 10-year relationship.

Attending a barbecue with Cleopatra's family, Isaac has awkward conversations with her family, and eventually takes a couple hits from a blunt. While high, Isaac converses with Cleopatra's aunt, who he seems to hear tell him she is lonely, and she urges him to "run".

Todd McCarthy of The Hollywood Reporter praised the film, and wrote: "Lemon represents a feature debut of unusual assurance and control with a style all its own."[13]
Owen Gleiberman of Variety gave it a mixed review: "Lemon is a comedy of miserablism that keeps poking you in the ribs — and, quite often, fails to hit the rib it’s aiming for. Yet it’s a watchable curio, because beneath it all the director, the Panamanian-born Janicza Bravo, has a more conventional sensibility than she lets on."[14]
