Damn the Defiant!

On the H.M.S. Defiant, during the French Revolutionary War, fair Captain Crawford is locked in a battle of wills against his cruel second-in-command Lieutenant Scott-Padget, whose heavy-handed command style pushes the crew to mutiny.
Defiant's crew is part of a fleet-wide movement to present a petition of grievances to the Admiralty. Violence must be no part of it. The continual sadism of Defiant's first officer makes this difficult, and when the captain is disabled, the chance for violence increases.
