All your favorite emojis live in the bustling city of Textopolis, hoping to be selected by their phone's user. Each emoji only has one facial expression that is, with the exception of Gene (T.J. Miller), an exuberant emoji who, because he was born without a filter, has numerous expressions.
Instead of being happy to be diverse and unique, Gene just wants to be "normal" like the other emojis. He gets his best friend Hi-5 (James Corden) and notorious code breaker emoji Jailbreak (Anna Faris) to join him on an epic "app-venture" through the apps on the phone to find the code that will fix Gene. They soon encounter a greater danger that's threatening the phone and the fate of all emojis. The three unlikely friends have to move quickly or their world will be deleted forever.
