Demonic vines grow underground and monsters invade the hell on earth.

Steve and Dustin stood in front of the dark basement entrance, filled with doubts and nervousness.They opened the heavy iron door, but what greeted them was silence.Steve suspected that Dustin was up to something, but Dustin's expression clearly meant he wasn't joking.He pointed to the depths of the basement, where there was a layer of creepy molted skin, as if telling some unknown secret.

Just as Steve called Dustin to come down and check, a loud bang broke the silence.The wall cracked and a huge monster burst out, digging an underground tunnel and quickly escaping.Its escape seems to indicate that a greater crisis is coming.

Although Jim and Will were rescued by laboratory staff, their hearts were full of uneasiness.Jim decided to ask the professor in the laboratory what happened.The professor took Jim underground and revealed the truth about the laboratory research - they had been exploring the mysteries of another world, and the recent research findings were closely related to the shadow monster that Will perceived.These monsters not only grow like vines, but can also open underground tunnels.

Will's condition was getting worse and he was screaming and feeling pain all over his body.Joyce felt sorry for her son, but was unable to provide help. She could only watch Will being taken into the operating room by the laboratory staff.After the operation, Will lost his memory, but he still remembered his good friend Mike.Mike stayed with Will throughout and listened to him talk about his feelings.

Will told Joyce that the laboratory personnel angered the “it”, and this “it” was the vine shadow monster.In order to verify whether there is a sensory connection between Will and the vines, the laboratory deliberately hurts the vines to make Will feel pain.The results of the experiment showed that Will did have some connection with the vines.However, a common clinical examination revealed that Will was in good health, which baffled everyone.

Joyce couldn't bear to let her son continue to suffer, and she stopped the laboratory personnel from further experiments.Will also found temporary peace.However, when Will was chatting with Mike, he suddenly offered to help the laboratory eliminate the vine shadow monster.Based on his memory, he pointed out a very important location for the shadow monster in the picture.

The laboratory immediately dispatched a specially equipped army to the location.However, as they approached the location Will said, several monsters suddenly appeared.These monsters were extremely ferocious, and members of the special biochemical team were eliminated one by one in the tunnel.Professors and experimenters witnessed all this in the control room, and they were shocked and overwhelmed.

At this time, Mike suddenly remembered the spy thing he had talked about with Will before.It turns out that it wasn't Will who became a spy, but the shadow monster who was secretly manipulating everything.Will cried and told Mike that the shadow monster asked him to do this and that it was all a trap.
