"The stakes are higher than ever for the time-traveling exploits of William "Bill" S. Preston Esq. and Theodore "Ted" Logan. Yet to fulfill their rock and roll destiny, the now middle aged best friends set out on a new adventure when a visitor from the future warns them that only their song can save life as we know it. Along the way, they will be helped by their daughters, a new batch of historical figures, and a few music legends - to seek the song that will set their world right and bring harmony in the universe."
I have to agree with magicmuggle01, I'd give it a chance because I loved the Bill & Ted movies back in the day too. I'll keep my expectations low though, I'm not expecting the same joy ride as the earlier movies provided with a fresh young cast and original story line. Party on dudes.
