Five-0 goes on a manhunt when a chemical spill permits six dangerous inmates to escape, including Kono's husband, Adam.
The episode starts with an explosion on a prison bus and someone is shot and killed.
- Steve tells Danny that Adam only has 14 months left on his sentence, but in the beginning when they are showing the "stats" on the 6 inmates, it says Adam has an 18 month sentence and that he has already served 186 days, which would mean he has about 12 months left on his sentence.
- Steve McGarrett killed 1 person.
- Masi Oka is credited, but does not appear.
