Spoiler alert! This article contains “Hawaii Five-O" spoilers. Read on if you would like to know what happens next before the new episode airs.

Previously, Lou Grover (Chi McBride) was the focus of the episode. He and his family were forced into hiding after a mob boss has returned to avenge the imprisonment and subsequent death of his father, whom Grover sent to jail. The team were able to go around the FBI and save Lou and his loved ones just in time.

“While Five-0 investigates the theft of a high tech, indestructible suit built for the U.S. military, Jerry helps his sister try to save a captive elephant,” stated the episode synopsis on Spoilers Guide.

In the next episode, titled “Kau Haunaele,” which means “Rampage,” Jerry and his sister will attempt to save a captive circus elephant that went on a rampage. They will have to think fast or the animal may risk being put down before people are hurt.

The Five-0 team will also be looking for a stolen military armored suit. The suit was supposed to be the newest and most advanced gear specifically made for the U.S. military. It is apparently indestructible so the person who ordered its theft appears to have sinister plans that may even start a war.

In the promo video, the starting scene featured people panicking on the streets as a huge elephant makes its way through traffic. The high-grade black and silver suit was spotted walking into a bank and firing its gun. It is most likely controlled by the unknown enemy after it was stolen. Some of the special suit’s abilities were presented, particularly its invulnerability. The military explains to McGarret (Alex O’Loughlin) that the suit was stolen. While McGarret contemplates on how to stop the suit, he was told that it was impossible.

The upcoming episode will reportedly also present NFL brothers Michael Bennett of the Seattle Seahawks and Martellus Bennett of the New England Patriots.

“Hawaii Five-0” will air next on April 15, 2016 on CBS in the US and on Channel 10 in Australia.
