Well, you probably know the deal by know. At least I hope you do. A team of adventurers realizes that when their last “heist” went to heck, the wrong person got the wrong item. And that they are getting back together to stop her from carrying out her evil plan.
At least that’s what the trailers and ads tell you.
The main plot line actually concerns Edgin (Chris Pine) breaking out of jail so he can go get his daughter back and rebuild his family. If it happens that he and the gang discover the evil scheme along the way and decide to stop it, well, why not?
Having actually paid to see it in a theater, I noted that the movie satisfies no matter what your level of D&D knowledge might be.
