Sammy was born 3 years after Tommy and came with several surprises. Tommy was looking forward to having a playmate he could protect and take on his explorations. What Tommy didn't expect is that Sammy would clearly become the leader as they embark on their island adventures. When Sammy turned 3 years old it was Sammy's idea to investigate the other side of the island. Just as they were on the verge of turning back, they noticed a large compound in the distance. There were several structures enclosed in a fence with strange-looking people inside. The newcomers to the island were a research team looking for a rare flower that had healing properties.

Unfortunately, two unsavory men had also crashed on the island during a storm and spotted Sammy at a distance but didn't see Tommy. When they returned to the mainland they contacted a notorious big game hunter to help them capture Sammy, thinking that Sammy was alone on the island. That was their first big mistake, but it wouldn't be their last. Would they be successful or did fate have other plans in store for them? Would they discover the other unique creatures that lived on the island?
