The Musketeers are on a dangerous mission to escort a decoy king, an idea of King Louis XIII. The mission is cursed from the beginning as each of the four Musketeers are embroiled in a fight of their lives; and for some of them, a fight for their very survival. None of them make it through this mission from hell unscathed--it will forever be etched in their memories as the worst mission ever. Unfortunately, this mission has dire and deadly consequences.
