A Summer Place
Tags: melodrama

Plot synopsis:
Alcoholic Bart Hunter (Arthur Kennedy), his long-suffering wife Sylvia (Dorothy McGuire), and their teenage son Johnny (Troy Donahue) operate a crumbling inn on Pine Island off the Maine coast. The inn was previously Bart's elegant family mansion in an exclusive resort, but as his family fortunes have dwindled, the Hunters are forced to rent rooms to paying guests, even going so far as to move themselves into the small guest house so their own master bedroom suite can be rented out. Bart receives a reservation request from an old acquaintance, Ken Jorgenson, who was a lowly lifeguard on the island twenty years ago, but is now a successful research chemist and millionaire. Ken wants to bring his wife and daughter to the island for the summer. Bart dislikes Ken and feels that Ken is just coming to lord his new wealthy status over Bart, who is no longer rich. Bart nearly refuses the request, but Sylvia insists that he accept because they badly need the money.
Ken (Richard Egan) arrives with his wife Helen (Constance Ford) and teenage daughter Molly (Sandra Dee). Helen and Ken have an unhappy marriage, sleep in separate bedrooms, and frequently argue, including over the proper behavior standards for their daughter. Helen is a prude who disapproves of Molly's developing figure and healthy interest in boys, particularly Johnny Hunter, who is also attracted to Molly. Ken is much more relaxed and permissive, and tries to teach his daughter that her natural desires are not shameful. Helen also tries unsuccessfully to put on airs and impress the upper class residents of the island, while Ken is not interested in pretense and is even happy to talk with older people who remember him from when he worked as a lifeguard.
As it turns out, Ken and Sylvia were lovers twenty years ago, when they were teenagers. It soon becomes apparent that they still love each other and have missed each other for many years, and that Ken returned to Pine Island in hopes of seeing Sylvia again. They had broken up because Ken was a poor college student, while Bart was the son of a rich established family, so Sylvia married Bart, and Ken, after seeing Sylvia's wedding announcement in the newspaper, married Helen. Both marriages were unhappy but Ken and Sylvia stayed in them because of their love for their respective children, Molly and Johnny. Ken and Sylvia find themselves drawn to each other again and begin secretly meeting every night. They are soon spotted by the island's night watchman, who informs Helen. Helen initially keeps quiet, planning to catch them in the act in order to ensure a large divorce settlement.
Ken goes on a business trip for a weekend, during which time Molly and Johnny, with Ken's permission, go sailing around the island. Their boat capsizes in rough water, stranding them on the beach overnight. The Coast Guard rescues them the next day, but Helen is suspicious that the teenagers were intimate on the beach although they deny it. Helen sends for a doctor to examine Molly to make sure she is still a virgin (which she is) and Molly becomes hysterical and runs away, causing Johnny to threaten to kill Helen if she hurts Molly ever again. Helen contacts law enforcement and then in a fit of anger reveals Sylvia and Ken's affair in front of Bart, Ken, Sylvia and Johnny. The Hunters and Jorgensons each go through an acrimonious public divorce, and Molly and Johnny are sent to boarding schools several states apart. Molly and Johnny are angry at Ken and Sylvia and stop speaking to them, becoming increasingly dependent on each other for emotional support despite Helen's constant interference and criticism of Molly's morals.
Ken and Sylvia eventually marry and move into a beach house. They talk Molly and Johnny into visiting them there, to which the teenagers agree largely because it will give them a chance to be together away from Helen, who is unable to prevent the visit due to a court order. During their visit, Molly and Johnny secretly consummate their love. Ken and Sylvia suspect that the teenagers are sleeping together and are concerned about the possible ill effects, but in view of their own past teenage history, feel they cannot order Molly and Johnny to stop loving each other. Soon after, Molly discovers she is pregnant, and she and John run away together planning to get married. They seek Bart's blessing, but he is about to be admitted to the veterans' hospital due to ulcers from his drinking, and drunkenly tries to talk them out of marriage, later calling Helen to let her know what happened. The local justice of the peace sees they are under legal age to marry, and turns them down. In desperation, Molly and Johnny go to the house of Ken and Sylvia, who are supportive. In the end, a happy John and Molly, just married, return to Pine Island for their honeymoon.
