Olelo Ho'Opa'I Make
The team investigate the death of a college professor while Kono is given the task of protecting a witness and Danny attempts to keep his nephew, Eric in line.
Hawaii Five-0 investigate when a university chemistry professor is found dead in an acid bath.
As they investigate the case,Danny Williams is tasked with babysitting his nephew, Eric Williams, one of Danny's unnamed sisters having sent Eric to Hawaii for fear that Eric will get into trouble while also hoping that Danny will be able to straighten him out.
Although Eric often plays jokes and takes things lightly, Danny isn't impressed and calls Eric out on it.
The team investigates the case, eventually learning that the professor missed lectures in order to pursue other projects, namely bringing back an extinct plant which can hold the key to curing a disease which the son of the professor's partner has.
The killer (whose identity was voted for by fans during the show and differed based on timezone) later attempts to murder Doctor Stevens in his camp, but Steve McGarrett and Chin Ho Kelly shoot him first.
Meanwhile, Kono is placed in charge of guarding Sang Min, who has returned to Hawaii to testify in a federal case.
Sang Min escapes custody to see his family. Kono arranges to have Sang Min transferred back to Halawa prison to be close to them.
Eventually, having learned a lot, Eric wants to work in the crime lab.
