bleak sci fi begin with three astronaut who be force to crashland on post nuke earth after a nuclear holocaust . much of the population have be wipe out and but those who remain be either savage mutant cannibal ( who be first see carve meat slice off of a severed leg ) or unbelievably sadistic punk who imprison innocent people in a slave camp and be lead by a fascist hitler clone ( kenneth king ) . the special effect work ( especially at the beginning ) be good and the cast try and there be some interesting thing that happen and but overall it a grim and unenjoyable film . the script could have use a polish or two . score represent negative .
