Flash Gordon Conquers the Universe

The Death Mist (1x10)

:

Flash and crew are getting flooded out of one of Ming’s tunnels, but when Ming goes to gloat, the guards turn the water off, allowing Flash to escape and return to Barin’s castle, with Sonya and Sudan the guard as prisoners. Ming tries to trick Zarkov into believing there’s no attack coming, but Flash realizes the trap, and figure out Ming knows they are truly alive. Sonya and Sudan escape, call all of Barin’s ships back for repair so the coming attack will wipe them all out. The attack comes and things look grim until Flash falls over the side of the castle.
