Based on a true story, INFINITELY POLAR BEAR is a funny and heartbreaking portrait of the many unexpected ways in which parents and children save each other.

The year is 1978. Cam Stuart, black sheep of an old New England family, is fresh off a manic-depressive breakdown. His wife, Maggie, has left him, taking their two young girls. Cam misses his family terribly; and when Maggie goes to New York City to get her MBA, she asks Cam to move in and take care of their daughters. Cam insists that Maggie return to help him every weekend, and eventually the four of them figure out a new and unconventional way to be a family.
