Guardians of the Tomb

Guardians of the Tomb is a 2018 Australian-Chinese science fiction horror thriller film directed and written by Kimble Rendall, starring Li Bingbing, Kellan Lutz, Kelsey Grammer and Wu Chun.

In modern day, Luke and Ethan are researching the myth of the emperor and eternal life in remote China for business man Mason.

Soon after, Mason convinces Luke's estranged sister, Jia (a venom and dangerous animals expert), to accompany him on a search for her brother.

The lightning storm outside sets the building on fire forcing the group to flee to the basement which has been lined with trigger webbing by the spiders.

When the emperor’s doctor reached Australia, he found out from one of the shamans that an elixir could be brewed to extend life but its ingredients came from a certain spider (the funnel web) and only at a certain time.

The shaman was only able to make a small sample of it, so the doctor caught hundreds of funnel webs and brought them back to China where for decades he experimented on them to mass produce the elixir for the emperor and himself (a later flashback reveals the spiders got loose killing all in the palace).

He attacks the group with a crossbow, injuring Jack but Luke springs the traps causing Mason to be shot with arrows.

The last room in front of the exit turns out to be the spider's nest, filled with thousands of funnel webs, egg sacks and a massive female.

The group start cautiously crossing the room whilst the female watches them, before she suddenly begins launching webs, two of which catch Chen and Gary who are then pulled to the ground where they are swarmed and consumed by the spiders.

The remaining few hastily try to figure out how to escape, realising it is another puzzle they quickly solve it which cause the ruins around them to start collapsing and burning.

A falling pillar smashes a wall, opening a passage to the outside and Jack, Luke, Jia and the young girl escape.
