There are huge holes in this fact pattern that would be important to answering it -- like, what is the daughter doing in Nevada in the first place? How long has she been here? Is there any kind of agreement -- oral or written -- indicating why she is here, or how long she should be here? All of those would be important to know before anyone would counsel you to engage in self-help (ie., swooping in and grabbing the child).
Obviously, the child's physical safety comes first, so do nothing that might provoke a physical confrontation. On all aspects of this matter, you need a much more in-depth analysis, starting with all relevant documents and probably including a detailed discussion of what is really going on, and why. There are a lot of grandparent-custody-or-visitation cases in Nevada; you can find information about them here:

Then you really, really should consult with qualified counsel.
