The medical examiner tells Nikki that the woman died from a coronary arrest due to what appears to be a lightning bolt. She tells her that it seemed like the woman had an ID badge around her neck, which is now missing.

A plasma physics professor named Otto Bahnhoff arrives at Charlie's office to examine the video of the attack. Floyd arrives and meets the team. Otto says he thinks the woman was killed by ball lightning. Charlie says it is difficult to control lightning. Otto says that he knows about a project called SHIVA where the government is working on controlling electricity. Floyd makes a call and confirms that SHIVA was shut down.

Nikki and Colby investigate a hanger at the base. Nikki finds a package of sucralfate which is prescribed to people with stomach problems. At night, Nikki, David and Colby stake out the target area. They see a van parked in the middle of the field. Inside the van, a group of men conduct an experiment that goes wrong. The van starts to shake then explodes.

The next day, David tells the team that they will have difficulty identifying the bodies. Don tells David he doesn't trust Floyd. Charlie examines the van and sees it has sophisticated equipement. At the lab, the ME tells Nikki she discovered the men who died in the van were engineers from a weapons contractor called Neox Industries.

David informs the team that they believe the woman who died is Cynthia Abbot who works for Neox. David meets with the CEO of Neox and asks him what his engineers were working on. The CEO says he signed a confidentiality agreement with the government and can't talk. They inform him that they found Cynthia's body. The CEO says Cynthia was not even working on the project.

Nikki meets with Cynthia's boyfriend who says he doesn't understand why anyone would hurt her. The team asks him if they can obtain a DNA sample to see if it matches the body.

Charlie find Floyd in their office. He says his department's purpose is to make sure projects come in on time and on budget. He says Neox has a contract to produce non lethal weaponry. He gives them Cynthia's laptop that the FBI recovered.

Amita tells Charlie that Cynthia emailed a message about Neox testing new weaponry. Amita says Otto sent her a document about drone based weapons. Charlie and Amita go to the field and are surprised by Floyd. They explain they are trying to figure out where the energy burst came from. They find a dead sheep and several burned objects. In the field, they find a crashed unmanned drone with a laser that can be used to channel a bolt of energy. Charlie figures they found the murder weapon.
