Although I can’t match that description to the trailer, IMDb has something similar:

A queen, desperate to find happiness in love, takes a daring step: she sends the powerful and feared witch Gray Alys (Milla Jovovich) to the “Lost Lands” to give her the magical gift of turning into a werewolf. With the mysterious hunter Boyce (Dave Bautista), who supports her in the fight against dark creatures and merciless enemies, Gray Alys roams an eerie and dangerous world. And only she knows that every wish she grants has unimaginable consequences…

So it might be a garbled version of the plot or it gets a lot wilder and weirder.
