In Our Nature(2012)

When Brooklynite Seth takes his girlfriend Andie to his family's weekend house in upstate New York for a romantic getaway, they are unexpectedly joined by his estranged father, Gil, and his much-younger new girlfriend, Vicky. The women carefully negotiate emotional minefields as they persuade father and son to share the house for the first time since the summer vacations of Seth's childhood. This unexpected family reunion in the great outdoors, fraught with tensions old and new, pushes them all to realize the bonds of family are always stronger and stranger than expected.
