The forest in Senegal, a country in western Africa, is full of the chimps' usual noises. Suddenly dogs bark. Larger male chimps drop from the trees to face the threat while the others climb to safety. Then the dogs' young human masters appear. One mother chimp with a tiny baby tries to run. The dogs attack and separate them. The two teenage boys quickly catch the baby chimp. But they don't act out of sympathy --- they save the baby so they can sell it. After the teenagers return to their hometown, they visit a man who is said to be very interested in chimps. When they ask the man, Johnny Kante, if he wants to buy the baby, he replies, "That's not what we do." Kante is a member of a scientific team. Although Kante is angry with the teens for capturing the chimp, he hides his anger and persuades them to take him to the baby chimp. Unsure of what to do next upon seeing the chimp, Kante calls Jill Pruetz, the head of the chimp research team. "I'm really worried," says Pruetz, doubtful that the mother is still alive. But knowing that wild chimps sometimes adopt orphans , Kante and pruetz decide they must try to return the baby chimp to its wild community. Kante pays another visit to the teenagers. After he explains how much trouble they are in, because chimps are an endangered species, he requests they should give him the frightened baby without payment. They agree.
