During a rescue, Mitch rescues the woman, while Craig is stuck with a 300-pound man. Craig is almost knocked unconscious by the man, but Mitch arrives just in time to return them to safety. Mitch is concerned about Craig's health after the rescue. He tells Craig that divorces can be tough and if he needs someone to talk to, Mitch will always be there to listen. Craig just tells him that everything is fine. Mitch and April decide that he needs to talk to Craig. Therefore he plans on taking him paddle boarding.

Just before they are about to go out on their boards, Craig tells Mitch that he has lymphoma. The doctors discovered it early and Craig might live for another ten years. When they have paddled out, they are caught in a fog. While they are waiting for the fog to disappear, Craig starts eating a candy bar that he had stored in a compartment of his wet suit. Of course Mitch wants some and they end up losing it in the ocean. Craig tells Mitch that he is going to break up with April. He does not want her to end up without a boyfriend when he dies. Mitch talks him out of it.

Later a shark arrives and knocks Craig off his board. Craig is knocked unconscious. After Mitch has scared away the shark, he rescues Craig.
