Webs is a 2003 science fiction-horror television film directed by David Wu and starring Richard Grieco, Colin Fox and Kate Greenhouse.
Four electricians, Dean, Junior, Ray and Shelly (nickname for Sheldon), are sent to cut off the power in a condemned building before it's torn down.
Upon breaking down a door they discover an old laboratory, which encloses an atomic pile (vintage nuclear reactor) powering a weird machine in the floor.
Dean falls through a dimensional portal that's created and Junior goes after him, while Ray and Shelly read a journal left behind by the scientists.
Shelly, by reading the journal, realizes that the researchers were attempting to make a gateway to a parallel universe and he and Ray decide to step through the portal.
Finding no one on the other side of the dimensional portal, Ray and Shelly set off and get a fright when Junior leaps out.
Junior, Ray and Shelly start celebrating, while Dean comes running back armed with a block of wood.
Dean meets the Old Man, who is revealed to be Dr. Richard Moreli, the inventor of the portal who got stranded here 30 years ago.
Dr. Moreli tells him when he opened the portal 30 years ago, it let in giant evil Spider Queens into this parallel Earth, who set out to enslave and devour most of humankind.
The survivors bring them back to the base, and Shelly and Moreli begin to build a new portal.
Dean, Crane and Elayna, meet up and go back for Moreli, but find Ray with a broken leg and alone.
