It's 17th century France and D'Artagnan (JUSTIN CHAMBERS) is a young man who's been trained by his older guardian, Planchet (JEAN-PIERRE CASTALDI), to become a Musketeer, one of the King's elite guards. Yet, D'Artagnan has an ulterior motive as he's searching for the unscrupulous man, Febre (TIM ROTH), who killed his parents before him some fourteen years ago.
Accompanied by Planchet, D'Artagnan heads for Paris where he hopes to find his father's former associate, Treville (MICHAEL BYRNE), an aged Musketeer. He discovers, however, that the Elite Guard is now in disarray. Cardinal Richelieu (STEPHEN REA) has been usurping power from the King (DANIEL MESGUICH) and Queen (CATHERINE DENEUVE) by using Febre as his enforcer, and Treville is now imprisoned for a murder he didn't commit.
To make matters worse, younger Musketeers, such as Aramis (NICK MORAN), Porthos (STEVE SPEIRS) and Athos (JAN GREGOR KREMP) are disheartened by the turn of events, and have no plans of supporting D'Artagnan in his cause. Things aren't completely dim, however, as the young Musketeer meets Francesca (MENA SUVARI), a chambermaid who just so happens to know the Queen due to her mother formerly serving as her seamstress and confidante.
Despite the odds, D'Artagnan sets out to rescue Treville, and manages to enlist the aid of Porthos and Aramis who are impressed by the young man's vigor and skill. From that point on, D'Artagnan does what he can to persuade his fellow guardsmen to protect the King and Queen from the Cardinal's nefarious plans, all while striving to avenge his parents' death.
