Can you solve the troll's paradox riddle?

You and your brother have discovered another realm and set off exploring the new wonderful world. Along the way, you see a troll catching creatures in an enormous net. The troll agrees to release the creatures if you can come up with a statement that is both truth and false. Can you come up with the correct sentence and force the troll to release them? Dan Finkel shows how. [Directed by Artrake Studio, narrated by Addison Anderson].
