Happy families are all alike, but every unhappy family is unhappy in its own way. Directed by Song Hae Sung (A Better Tomorrow), Boomerang Family brings together the impressive cast of Park Hae Il (War of the Arrows), Kong Hyo Jin (Love Fiction), Yoon Je Moon (Dangerously Excited), Yoon Yeo Jeong (The Housemaid) and Jin Ji Hee (Moon That Embraces the Sun) to form a dysfunctional family forced to live together under one roof. Faced with both a marital and career crisis, struggling director In Mo (Park Hae Il) has no choice but to move back home and live with his mother (Yoon Yeo Jeong). His sister Mi Yun (Kong Hyo Jin) is also getting a divorce and planning to move back home with her teenaged daughter (Jin Ji Hee). Their older brother Han Mo (Yoon Je Moon), who's been in and out of prison, has been living at home all this time, and he is not happy with the sudden intrusion. With nowhere to go, the three troubled siblings have no choice but to put up with each other again as they try to get their messy lives back in order.
