Season 8
McGarrett, Danno and the Five-0 task force continue to wipe out the crime that washes up on the islands’ sun-drenched beaches, and this year are joined by new and old friends to help in their mission. Whether dealing with an infamous pyromaniac loose in the jungle, a devious black-hat hacker, stopping the dangerous Yakuza crime syndicate or planning to open a very bro-mantic restaurant, Five-0 continues to protect their loved ones, Hawaii’s citizens and visitors to the 50th state.
