Charles Farmer (BILLY BOB THORNTON) was once an aspiring astronaut with dreams of traveling into Earth's orbit. A family situation, however, forced him to leave the agency and now he's a farmer living with his supportive wife Audie (VIRGINIA MADSEN) and their three kids, teenager Shepard (MAX THIERIOT) and his younger sisters Sunshine (LOGAN POLISH) and Stanley (JASPER POLISH). Audie's father, Hal (BRUCE DERN), also lives with them.
Yet, Charles can't get the thought of outer space out of his blood, so he's taken matters into his own hands by building his own rocket in his barn. His passion, however, has not only put a partial strain on his marriage, but also a greater one on the family finances.
Things get even worse when a variety of federal officials show up once they get wind of his rocket building. Fearing that he's potentially a terrorist, the likes of FAA Head Honcho Jacobson (J.K. SIMMONS), FBI Agents Killbourne (JON GRIES) and Mathis (MARK POLISH), and a host of others descend upon his farm and the nearby small town. Even a current astronaut (BRUCE WILLIS) shows up to try to convince Charles that the feds won't let him fly.
Undeterred, but needing help, Charles contacts local lawyer Kevin Munchak (TIM BLAKE NELSON) who makes a few calls, resulting in the press also showing up. From that point on, and with money running out and family tensions mounting, Charles must overcome a variety of obstacles as he tries to pursue his goal of launching himself into orbit.
