Missing a Climax

I recently watched a movie about a woman whose estranged husband faked his and their son’s death—lost at sea during a storm. Fourteen years later she sees her husband on a friend’s vacation video with their son, now grown up. He runs a diving charter on a Caribbean island so she flies there to get her son back.  There’s lots of good tension with the possibility of a hurricane hitting the island in a few days, trouble with the law because she doesn’t have a passport and has lied about losing it, and the fact that the husband and son are gone on a charter and may not be back in time before the law finds out she’s lying and/or the storm hits. To make matters worse she finds out that her husband is the most popular guy on the island—very generous with his time and always helping people out. People consider him a saint. Great set-up for the main character. She’s facing all sorts of problems and could even end up in jail. She only has an old photo of her son at age 3 as proof. She burned everything when she thought they had died. The husband comes back and then takes off alone for another island, leaving the son behind. Perfect chance for the mother to bond with the kid. By now the police have found out she lied about the passport. She tells the officer the truth and he forbids her to say anything to the kid while he checks out her story. But instead of checking it out, he calls the husband and leaves...
