Set in 1944, Valiant (Ewan McGregor) is a woodland pigeon who wants to become a great hero someday. When he hears they are hiring recruits for the Royal Homing Pigeon Service, he immediately sets out for London. On the way, he meets a smelly, but friendly pigeon named Bugsy (Ricky Gervais), who joins him, mainly to get away from clients he cheated in a game of find-the pebble, and helps him sign up for the war.

Super spy Lance Sterling and scientist Walter Beckett are almost exact opposites. Lance is smooth, suave and debonair. Walter is not. But what Walter lacks in social skills he makes up for in smarts and invention, creating the awesome gadgets Lance uses on his epic missions. But when events take an unexpected turn, Walter and Lance suddenly have to rely on each other in a whole new way. And if this odd couple can't learn to work as a team, the whole world is in peril.
