The Duplass brothers are back with their singular knack: treating us to a tingling, irresistible experience of utter discomfort—suffused with pathos, romance, irony, and a little dollop of horror. This time they intrepidly mine Oedipal terrain to wrestle with stirring, profound questions about the obstacles to human intimacy.

Alone and acutely depressed, having just learned of his ex-wife’s wedding plans, John can’t believe his luck when he encounters beautiful, charming Molly at a party. The two get along famously and launch a passionate affair—until Molly’s 21-year-old son, Cyrus, enters the scene. Will Molly and Cyrus’s deep and idiosyncratic bond leave room for John?

Cyrus becomes a dark, poignant, sometimes hilarious war dance as Molly, Cyrus, and John walk the line between creepy and sympathetic. Each member of this awkward triangle teeters somewhere between bare honesty and furtive manipulation as he or she lets loose all manner of dysfunctionality. The excruciating, delightful fun is seeing where the boundaries ultimately land.
