Sarah (Riley Keough) is a stay at home mom whose husband frequently travels for work and is dismissive of Sarah's concerns about his absences. Overwhelmed by the isolation of taking care of her toddler daughter, she calls her best friend Mindy (Jena Malone), whom she has not seen in years, and the two depart on an impromptu roadtrip together with Sarah's toddler daughter. The two women discuss their different lifestyles with Sarah believing that Mindy is free-spirited and promiscuous. After a night recalling their sexual experiences in college, the two end up kissing, which leads to them being physically intimate. The day after, Mindy is hurt after Sarah seems to treat the experience nonchalantly, thinking it happened due to the spark of the moment and Mindy's promiscuity. When they stop at a convenience store, Mindy purchases a ticket back to her home in New York City and abruptly leaves.
