seven young people go to the forest look for a bear . soon they be all stalked and viciously murder by a crazy vietnam veteran . trampa infernal be a pretty entertaining mexican slasher that remind me a lot the zero boy . the film be fast paced and there be some good death scene like throat slash or axe in the neck . unfortunately there be not much gore and so fan of grand guignol will be disappoint . however if you be a fan of slasher movie give this rarity a look . mexican horror flick be quite obscure ( i have see only alucarda and don not panic ) and so this should be another reason to see this enjoyable slasher . my rating represent positive . highly recommended .
