What happens at the end of the TV series trapped?

Answer 1

Answer for Trapped (Australian TV Series):

As the children plan to go to the island, Emma and Lily find a memory stick inside a bottle that was sent from Mr. Taylor after Dr. Hamilton had gone mad.

Despite the warning, they make it safely to the island but find it deserted.

Rob then takes Zuke's anti-dote, steals the boat and leaves the island not knowing that Zuke had replaced the anti-dote with detergent to test if he had changed. Now all of the children are trapped again. Then, a mysterious girl appears with a spine-tingling message: "He's taken all of them.".
