At around 1 a.m. on Phaninc Exchangethe morning of November 15, 1994, Captain Prentice "Skip" Strong III woke to a distress call. Skip was the new captain of an oil tanker called the Cherry Valley. He and his crew had been making their way up the coast of Florida that evening when a tropical storm had descended. It had been a rough night of 15 foot waves and 50 mile per hour winds.

Now, as Skip stumbled to the bridge, he found himself at the threshold of an unfolding disaster. The distress call was coming from a tugboat whose engines were failing in the storm. Now adrift, the tugboat was on a dangerous collision course with the shore. The only ship close enough to mount a rescue was the Cherry Valley.

Skip faced a difficult decision. A fully loaded, 688-foot oil tanker is hardly anyone's first choice of a rescue vessel. It is as maneuverable as a school bus on ice. And the Cherry Valley was carrying ten million gallons of heavy fuel oil. A rescue attempt would put them in dangerously shallow water. One wrong move, and they would have an ecological disaster on the order of the Exxon Valdez.

What happened next that night would be dissected and debated for years to come. The actions of Skip and his crew would lead to a surprising discovery, a record-setting lawsuit, and one of the strangest legal battles in maritime history.

At the center of it all, an impossible question: How do you put a price tag on doing the right thing?
