Based on the novel by Bernard Cornwell, "Sharpe's Waterloo" brings maverick British officer Lt. Col. Richard Sharpe to his last fight against the French, in June of 1815. Sharpe is assigned to the Prince of Orange's staff, and is rejoined with Sgt. Harper (retired) and riflemen Hagman and Harris at the famous battles of Quatre Bras and Waterloo. Not only must Sharpe deal with incompetent orders from the Prince of Orange, that lead to slaughter, he confronts his wife's lover, Lord Rossendale, in the midst of battle. The film climaxes as Wellington's small army 'holds the line' against Napolean's veteran Imperial Guard.
