Bill & Ted Face the Music follows the same model as the first two installments of the trilogy; Bill and Ted travel through time and get into a world of shenanigans. The now middle-aged friends will set out on a new adventure to fulfill their "rock & roll destiny" after a visitor from the future warns them that only their song can save life as we know it and bring harmony to the universe. Along the way, they'll be helped by their families, old friends, and a few music legends.
