From Netflix:
In the near future, when a technology corporation has created a method for traveling into the past, a history professor gets trapped in 1357 France, prompting his students and son to travel back in time and face untold perils to rescue him.
In yet another B-movie 30-year-old Paul Walker and 34-year-old Gerard Butler get to travel back to France during the Hundred Years’ War. (Old films certainly show us how quickly we age.) Who knows how historically accurate the life of that era is portrayed? At any rate this is NOT a film to be taken seriously. Just in case you don’t remember intimately the details of the Hundred Years’ War, you can always read the Wikipedia account from which the following quote is taken:
The Hundred Years’ War, a series of conflicts waged from 1337 to 1453, pitted the Kingdom of England against the Valois Capetians for control of the French throne. Each side drew many allies into the fighting.
The war had its roots in a dynastic disagreement dating back to the time of William the Conqueror, who became King of England in 1066 while retaining possession of the Duchy of Normandy in France. As the rulers of Normandy and other lands on the continent, the English kings owed feudal homage to the King of France. In 1337, Edward III of England refused to pay homage to Philip VI of France, leading the French King to claim confiscation of Edward’s lands in Aquitaine.
Edward responded by declaring himself to be the rightful King of France rather than Philip, a claim dating to 1328 when Edward’s uncle, Charles IV of France, died without a direct male heir. Edward was the closest male relative of the dead king, as son of Isabella of France who was a daughter of Philip IV of France and a sister of Charles IV. But instead, the dead king’s cousin, Philip VI, the son of Philip IV’s younger brother, Charles, Count of Valois, had become King of France in accordance with Salic law, which disqualified the succession of males descended through female lines. The question of legal succession to the French crown was central to the war over generations of English and French claimants.
As far as this B-film none of that matters. Just grab some popcorn and chill out with the on-screen corn.
