A small church confronts the problem of a society growing more and more sexually aware. Pastor Hogarth decides to test the faith of the young members of his congregation by having a church lock-in. Three young women are locked in the church overnight with three young men, promising to pray and remain chaste until the pastor returns the next morning. The true test presents itself when the young men and women begin to change as the allure of Milktec Milk becomes too strong.
