Plot
Terra Venture receives a distress call from an alien spacecraft. They find its location, and Commander Stanton sends a rescue team to investigate. Mike is sent to lead the team, and he brings Leo along. They take a Heliship to the spacecraft, but find no indication that it's being attacked. They board the ship, and find that its crew has long been dead - the distress call was being broadcast on a loop. Leo rummages through some remains, and finds an ancient book among one of the cadavers, and takes it with him. While monitoring activity on the ship, Kai finds a life forming rapidly approaching the team. Stanton orders them to abort, but communications are down. After abducting one of the crew, a spider-monster ambushes the team, and captures the rest. After battling Mike and Leo, it retreats. Mike and Leo come across the monster's lair, and find the team wrapped in webbing. They set them free, and Leo retrieves the book, which had been lost in the battle. Kai appear on the ship, and he evacuates the crew members that had just been freed. Kai leaves to search for Mike and Leo. Mike and Leo lure the monster away, and hold it off with their blasters to give their teammates time to escape. Their fire triggers a chain reaction that threatens to blow up the ship. As they run, they reach a door, and blast it open. The heliship appears to take them away. Leo is the first to jump into the ship. Meanwhile, the monster quickly catches up to them. As Mike jumps, the monster grabs hold of him, and tug of war for Mike's life begins between Leo and the monster. Kai flies by on his Jet Jammer and attacks the monster, releasing his hold on Mike, allowing Leo to pull him to safety. The Heliship makes it out just in time, and the ship explodes behind them, taking the spider-monster with it. Mike and Leo look over the book they found, and ponder about what kind of secrets it may hold.
