In the Spider's Web

When a team of backpackers sets out to explore the Indian jungles, one of them is bitten by a poisonous spider. Forced to seek the help of Dr. Lecorpus (Lance Henriksen), an American physician living in a local village, the group quickly discovers that the village has several secrets. As they learn of a venomous ritual in which a crawling army of spiders feasts on dead corpses, they unravel Dr. Lecorpus involvement in the ritual and his plans which are beyond anything any of them could have imagined.
