Remi and Barnes, two very different teenagers, meet by chance in the winter of their senior year, then spend four days together over the course of a year that will change their lives forever.

Following a chance encounter, wunderkind Remi and music-obsessed slacker Barnes become inexorably entwined in each other's lives. As winter turns to spring and spring turns to summer, the two find themselves falling in love. But with Remi heading to Harvard in the fall, the young couple are forced to reevaluate what's truly important to them.
