When teenager Robyn looks up from snorkeling, she thinks she can see dolphins leaping in the distance. It is a beautiful place, a little beach just off beautiful Captiva Island, Florida. There are shells and wildlife. A swim across this natural, untamed beach is her one goal, the one plan she held on to through her whole, week-long vacation. It will be a wonderful, never-to-be forgotten experience, she is sure. And, Robyn’s younger sister Rue is, like always, spoiling everything.

In a perfect piece of bad timing, a motorboat chugs up the beach, with a more than averagely cute guy preparing for a swim. Will his arrival makes things better or worse? Jump right in – the water is fine!
