The B-movies that are shown on channel five (UK) have three main plots...

Plot 1
A plane flight crash, survivors left in a remote and icy location, two of them survive but not without the need for amputative surgery on their toes to deal with the frostbite they have suffered. Happily ever after (they generally leave the story of their recovery sans-toes to the imagination).

Plot 2
When she hears that her daughter is unable to have children, X offers to carry the child on her behalf. The tale of love, joy and tension that this incurrs.

Plot 3
A 'cop' whose partner was killed in action goes in search of revenge.

Have I missed any out?
