Secrets of an Island

Two people were picked to go undercover for two months on a getaway island run by the church. They knew each other but had the reaction of oil and water when placed in the same working environment. When they were told they had to pose as a married couple they made a deal to try to get along for the sake of the mission. Things changed as they got to the island and them pretending to be married was no longer a part of the mission that they were first assigned too.
The mission changed as the days went by and they had to learn to live with each other until a surprise revelation and a new begging changes the worlds of those two people.
