One night out of the blue, restaurant owner/chef Davis Green (Joseph Cross, LINCOLN) is approached by Alexis (Adelaide Clemens, NO ONE LIVES) who claims to be his cousin. Caught in a hug with the strange young woman by his depressed and volatile dancer girlfriend Cassie (Deborah Ann Woll, TRUE BLOOD), Davis is disinclined to believe Alexis since he has grown up believing that his developmental psychologist father Ronald (Richard Schiff, SE7EN) has no siblings, only to learn from his Grandpa Howard (George Riddle, ARTHUR) on his deathbed that "we don't talk about Joshua" before the older man has an attack and falls into a coma. When his father refuses to tell him anything about his uncle and an entire side of the family he never met, and on the outs with Cassie, Davis heads upstate to Dustin, New York and discovers that his uncle's family run a thrift store/marijuana dispensary and live on a remote farm outside of town. Reconnecting with Alexis, he then meets her sisters Annie (Yvonne Zima, IRON MAN 3) and Amanda (Vanessa Zima, ULEE'S GOLD) and feels an intoxicating sense of familial warmth alien to him as the only child of two cold Yale academics. Although he poses as Alexis' boyfriend, he is immediately recognized by Uncle Josh (Ricky Jay, THE PRESTIGE) - a Harvard-educated philosopher turned backwoods pot farmer - who makes apologizes for not being around while he was growing up but is violently adamant about not making peace with Davis' father. Feeling unwelcome, Davis prepares to leave until he and Alexis stumble across Josh's shack in the woods and discover a home movie that suggests that a woman was the cause of the "unresolvable" enmity between their fathers. When Cassie turns up to tell Davis that his grandfather has died, Alexis - desperate to hold onto Davis - decides that the scattering of his ashes at the family cabin - would be the perfect opportunity to reunited the family, unwittingly setting them on a violent collision course that will reveal shocking family secrets both old and new.
