The men will learn that frogs are no longer the biggest threat. Caguax unleashes the darkest Taino curse, known as the Seal of Guacar, as he seeks to take people's souls to feed the 'great Taino beast'. Guacar and his army of killer frogs aim to restore the glory of the Taino Indians.
Justin, Chisto, and Matt will soon find out that the hardest obstacle won't be the frogs or ancient temples. An old foe will return from the dead looking for revenge. An old friend will turn on them in exchange for power. Finally, Caguax will use the men's dark pasts against them as he reveals that his plan was carefully engineered thousands of years ago.
The crew is closing in on reversing the curse, but Caguax will prove himself to be the personification of evil. The question remains, is Caguax the true evil one or is there someone greater pulling the strings? As the men will learn, the dark history of Puerto Rico was never meant to be discovered. It was meant to remain shrouded in mystery.
Perhaps the most important thing... Hate might just be the strongest emotion within mankind.
