1813, and Horatio Hornblower is propelled toward the heart of the French Empire and his old enemy, Napoleon. Sir Horatio Hornblower has received strict and highly confidential orders from the highest rank: he must embark upon a grave and perilous mission to recapture the Flame in the Bay of Seine, where the brutal and foul-tempered Lieutenant Augustine Chadwick is being held prisoner by a mutinous crew. Rescuing the Lieutenant demands all of Horatio's spirit and seafaring prowess - for at the same time, he must contend with capturing two French cargo vessels and take part in negotiations to topple the faltering Napoleon once and for all.
