McGarrett's sister, Mary, is arrested by TSA agents for trying to smuggle $20 million worth of conflict diamonds on a flight, but McGarrett doesn't believe his sister is guilty of the crime. Mary insists that she was forced to commit the crime by an unknown man, who threatened to kill her coworker Angela. Five-0 then plans to put the diamonds on a direct flight to New York to save Angela, but the police officers escorting the diamonds are killed and the diamonds are stolen. With help from Chief Fryer, Five-0 tracks down August Marsh, an ex-con who served 30 years in prison for smuggling; if someone wants to move $20 million in diamonds, he's sure to know about it. March helps the team stage a sting, where they learn that the mastermind of the diamond heist was Kaleo, whom they put away in episode 107. Eventually, Five-0 figures out that Angela had been working for Liberian diamond smugglers for a while, and that she decided to steal the diamonds for herself. This More...is enough evidence to clear Mary of charges, despite Angela still being on the lam. Unbeknownst to the team, Angela arranges to sell the diamonds to March, who promptly kills her and takes the diamonds for himself.
