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. Cam Stuart (Mark Ruffalo), who struggles with manic depression, spends his days mushroom-hunting, cooking elaborate meals or working on one of his many half-completed projects. When Cam has a manic breakdown that lands him in a mental hospital, his wife Maggie (Zoe Saldana) and their two young daughters are forced to leave their house in the country and move into a cramped apartment in Cambridge. Broke, stressed and overwhelmed, Maggie applies to business school and is accepted to Columbia University’s MBA program—leaving Cam the primary caregiver for the girls while she completes her degree. But the two spirited girls are not interested in making things easy for him. With Maggie away in New York, Cam quickly realizes that he’s in over his head. Over the course of the next 18 months, as Maggie rushes to complete her degree, he learns, through trial and a lot of error, how to take care of his precocious daughters as well as himself.
