A new documentary tells the heartwarming story of an aging veteran's decades-long bond with a giant manta ray off the coast of Mexico.

• The film follows Terry, a U.S. veteran who spent years diving in Baja, Mexico, where he befriended a 22-foot oceanic manta ray he named Willie.
• Their nearly 20-year relationship pushed Terry to become an ocean conservationist.
• Now in his 80s, Terry takes one last trip back into the water hoping to find Willie again and bring the friendship full circle.
• The documentary, from an Emmy-winning director, is built around underwater footage of the pair together.
• A local screening is set for this Sunday afternoon at a historic theater.

Outlook: The film opens to the public with its special screening this weekend, giving audiences a close-up look at the reunion dive.
