ONSLOW COUNTY -

CAMP LEJEUNE, N.C. (AP) - A documentary about a Marine veteran's fight to reveal the truth about contaminated drinking water at Camp Lejeune will premiere at the Tribeca Film Festival in New York City.

The film's producers say "Semper Fi: Always Faithful" will have its first official showing at the festival, which opens Wednesday. The film follows retired Master Sgt. Jerry Ensminger's search for answers after his 9-year-old daughter Janey died in 1985 while the family was living at Camp Lejeune.

Ensminger is a former drill sergeant who lives in Onslow County. He helped uncover details about contaminated drinking water at Camp Lejeune. A million people may have been exposed to the water, and thousands believe the poisons caused illnesses that they or their family members suffer.

The festival continues through May 1.
