Stuck at home with her three-year-old daughter Jessie (Jessie Ok Gray) with her husband Dean (filmmaker Cary Joji Fukunaga, SIN NOMBRE) constantly traveling for work, Sarah (Riley Keough, KISS OF THE DAMNED) is feeling the strain of isolation until more worldly college friend Mindy (Jena Malone, DONNIE DARKO) pays a sudden visit. They take Jessie along with them on an impromptu road trip and the drink soon flows freely as they reminisce about their college days and inhibited Sarah intends to show Mindy that she is not the stick in the mud she was in college but instead reveals her discomfort with some of the things she and her husband have done to spice up their love life. A hangover gives way to sexual experimentation and, although it is Sarah who is more outwardly unnerved, it is Mindy who suddenly leaves in the middle of the trip. Three years later, Sarah is separated from her husband and taking daughter Jessie along with her to the upcoming nuptials of Mindy and fiance Leif (Ryan Eggold, TV's THE BLACKLIST). Although not part of the wedding party, Sarah puts herself out to help with the preparations only to feel like she has been replaced in Mindy's life by Leif and his fun-loving maid-of-honor sister Chloe (Amy Seimetz, UPSTREAM COLOR). As the wedding day nears, however, Mindy's insecurities come to the fore (with a little help from estranged mother Rosanna Arquette) and she tries to figure out whether she is running from or to something with her marriage and Sarah realizes just who is really important in her life. Told in a loose and distant fashion, the film's central relationship is not particularly compelling but Sarah's loneliness and sense of stasis is affecting, and the central pair do manage to bring the film to life a little in the final third. Arquette, Eggold, and songwriter Marshall Chapman (as Leif's mother) contribute engaging supporting performances despite being given very little to do.
