Chipmunk to grey squirrel

A struggling songwriter named Dave Seville finds success when he comes across a trio of singing chipmunks: mischievous leader Alvin, brainy Simon, and chubby, impressionable Theodore.

Through a series of misunderstandings, Alvin, Simon and Theodore come to believe that Dave is going to propose to his new girlfriend in New York City - and dump them. They have three days to get to him and stop the proposal.

Surly, a curmudgeon, independent squirrel is banished from his park and forced to survive in the city. Lucky for him, he stumbles on the one thing that may be able to save his life, and the rest of park community, as they gear up for winter - Maury's Nut Store.

When the evil mayor of Oakton decides to bulldoze Liberty Park and build a dangerous amusement park in its place, Surly Squirrel and his ragtag group of animal friends need to band together to save their home, defeat the mayor, and take back the park.

Decades since their successful television series was canceled, Chip has succumbed to a life of suburban domesticity as an insurance salesman. Dale, meanwhile, has had CGI surgery and works the nostalgia convention circuit, desperate to relive his glory days. When a former cast mate mysteriously disappears, Chip and Dale must repair their broken friendship and take on their Rescue Rangers detective personas once again to save their friend’s life.
