Ha'uoli La Ho'omoaika'i
McGarrett and Grover become unlikely partners when they are assigned by the Governor to deliver a warrant to a young hacker which later becomes an issue of national security, but all is not what it seems...
Kono helps Five-0 minus Danny, who is in New Jersey with his family to celebrate his father turning 60, capture Sato, who reveals that Adam is not dead; Kono leaves again to find him.
Afterwards, Governor Denning forces Grover and McGarrett to work together to serve an arrest warrant to Ian Wright for unpaid parking tickets. After arriving in his home, the two are ambushed, and Ian is kidnapped.
Five-0 discover that the kidnappers are professional bank robbers, and Ian is also an expert computer hacker who helped the gang rob a bank. After capturing the robbers, it is revealed that Ian was the ring leader all along, and was using his computer program on the bank as a test for further attacks.
They eventually find him at Honolulu International Airport, where he reveals that he hacked the flight path of a Hawaii-bound airliner and will crash it in the Pacific unless he is allowed to leave for a flight to Pago Pago.
Grover and McGarrett play into his demand until Catherine tracks and shuts down Ian's computer. However, Ian somehow sneaked out of the plane and is at large.
Ian later taunts McGarrett through messages on a hacked ATM, to which McGarrett tells him he will catch him next time.

- The song playing in the background when Steve, Grover and the SWAT team confront Nick at the airport is Imagine Dragons- Radioactive.
