Our Friend tells the true, inspiring, heartbreaking and beguiling story of the Teague family-journalist Matt (Casey Affleck), his vibrant wife Nicole (Dakota Johnson) and their two young daughters-when their lives are upended by Nicole's diagnosis of terminal cancer. As Matt's responsibilities as caretaker and parent become increasingly exhausting and overwhelming, the couple's best friend Dane Faucheux (Jason Segel) offers to come and help. But when Dane recognizes the unrelenting toll being taken on Matt, Nicole and the two girls, he puts his life on hold to remain with his friends to the very end. The impact of this generous, albeit complicated, gesture proves greater and more profound than anyone could have imagined.
