Flash Gordon

King Zero of the planet Artico is using a climate-changing ray to cause snow to fall continuously on Mongo, disrupting and threatening life on the planet. Flash leads an attack on the ice planet Artico, but is captured and put to work under the sea harvesting seaweed. Dale has stowed away in Flash's ship and is also captured, but she is kept in the King's castle because the King is infatuated with her.
