They have a blast in Acapulco; they dine, dance, and end up in bed together. The next morning, Gloria has already left by the time Phillip wakes up. He looks for her, then finds out via videotape explanation that she's getting married next week and he was supposed to be her last fling. Phillip tries to find her; when he finally does, he tries to stop the wedding and convince Gloria that they belong together.
