Five enthusiast explorers; Cash (Anthony Sharpe), Eric (Luke Mitchell) Jennifer (Jessica McNamee), Victor (Benjamin Hoetjes) and Yolanda (Amali Golden) go to check out the cave that Cash previously discovered. Cash brushes off a storm warning from the weather app and they continue on into the cave. They follow a tunnel down to an open lake. Unbeknownst to the group it begins to rain and the cave begins to flood, soon the path they came in is now submerged underwater.
They begin to look for a way out but are unaware of the presence of the beast. Victor sees something in the water and leaves the group to retrieve it. He is attacked by the beast but survives with critical injures. Cash and Eric leave to look for an exit while the others stay behind. Swimming back underwater to the tunnel that they came through, they reach the exit and find it’s blocked with rocks. They then decide to go back and look for another way. Eric’s foot gets trapped between some rocks and nearly drowns while Cash makes it back to the first tunnel, but is soon attacked by the beast and killed. Eric reaches the tunnel only to see Cash’s headlight in the water. He returns to the group. (to be continued)
