Reuben Feffer thinks he's found the love of his life but on his honeymoon he discovers her cheating on him with a scuba instructor. Reuben travels back home to get his life on track. On a night out with best pal, Sandy Lyle, Reuben discovers an old school friend, Polly Prince. Reuben feels a connection straight away, and tries constantly to get her to like him. But it's not going to be easy for Reuben, especially when he spends his days calculating risks, and when someone unexpected turns up.
At around 6:30, the scuba diving instructor invites the newlywed couple on the beach to learn scuba diving with him. He's naked and the wife can see his dick and when the guy points to his boat, the wife comments that "It's very, uh... big," but she's looking at the guy's dick, not his boat. Later, the husband leaves his wife in the care of the scuba instructor to prepare a surprise dinner for her back in their hotel room. When he comes back to the instructor's boat, he finds the two fucking instead of having a scuba diving lesson.
