Hawaiʻi Island is losing a resident to overdose every eight days, and a grassroots task force is pushing back with a new documentary meant to put faces to the numbers.

• The Hawaiʻi Island Fentanyl Task Force formed five years ago after a 14-year-old girl in Kona died of a fentanyl overdose.
• The effort pulls together police, first responders, and local leaders to cut both supply coming onto the island and demand for it.
• Native Hawaiians are hit hardest — about 60% of the people served by the Big Island Substance Abuse Council are of Native Hawaiian descent.
• A new documentary, "Tidal Wave," tells the stories behind the overdose deaths and was made with help from local teenagers on the task force's youth advisory team.

Outlook: "Tidal Wave" premieres Friday at 12:30 p.m. on KITV, with replays Sunday afternoon and Monday evening.
