In the forests of the Pacific Northwest, a father (Viggo Mortensen) devoted to raising his six kids with a rigorous physical and intellectual education is forced to leave his paradise and enter the world, challenging his idea of what it means to be a parent. Captain Fantastic radiates genuine respect for existing in harmony with nature without skimping on the youthful need to rebel and see the world in full.
The film offers a critical view on home schooling and contributes in a unique way to the public discussion on advantages and deficits of alternative education models.
