H.M.S. Defiant

During the Napoleonic Wars, Captain Crawford (Sir Alec Guinness) takes command of H.M.S. Defiant and is ordered to rendezvous with the fleet in Corsica. With his son aboard as a new midshipman, Captain Crawford takes an even hand with his crew. This does not sit well with his second-in-command Lieutenant Scott-Padget (Sir Dirk Bogarde), a cruel officer who is also well connected, and someone who has proven to be the downfall of his previous commanding officers. As a battle of wills ensues, Scott-Padget uses Crawford's son in an attempt to get Captain Crawford to lash out against him. With the men on the verge of mutiny, they must also face the enemy.
