Echo Beach (2008)

The quiet life of a Cornish beach resort is disturbed by the arrival of "newcomers" who are actually relatives of leading businessman Mark Penwarden, who has an old, deep grudge against his brother Daniel, who returned years after a tragic boat incident to open a surf shop. Their children engage in romantic friendships and rivalry with each other and a few other locals, further complicating the fraternal households' entanglement.
