Based on the novel by Bernard Cornwell, "Sharpe's Waterloo" finds life seeming to have settled down for British officer Richard Sharpe (Sean Bean) as he enjoys a much-deserved rest at a French chateau with his new love, Lucille. However, the news of Napoleon's return from exile drives Sharpe back to the army for 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. It is here that Wellington's small army must 'hold the line' against Napolean's veteran Imperial Guard...
