In the New York metropolitan area, Bill McCabe robs a computer store with the assistance of his girl friend, Vera, and friend, Frank. Before leaving, Frank hands Bill a consolatory $3,000, indicating that he and Vera have decided to partner and work on their own terms. Bill is stunned. He goes to a coffee shop, where his younger brother, Dennis McCabe, informs him that their father, William McCabe, suffered a stroke. At the hospital, a nurse fawns over the McCabe brothers, expressing admiration for their father, who was a professional baseball player in the 1950s. She refuses to believe allegations that he set off a bomb at the U.S. Pentagon twenty years ago, but another nurse retorts that if the old man was innocent, why did he flee his hospital room? Later, Dennis and Bill discuss the bizarre events with their mother. She gives them a photograph with a phone number and the word “Tara” scrawled on the back, leaving it to them to find the fugitive. Although the phone number is disconnected, the brothers follow a hunch to Lindenhurst, an unincorporated community on Long Island, New York. There, Dennis asks Kim, a sullen Catholic schoolgirl, for information about the area. A nun admonishes Kim for speaking to a stranger. Kim blurts out, “Sagaponack!” as she runs to the bus. That night, Dennis and Bill argue about whether or not their father is a criminal. Bill condemns the man as a radical, before declaring he is brokenhearted by Vera’s betrayal. He announces his intention to seduce the next blonde woman he meets. The next day, Bill swaps his handgun in exchange for a motorcycle. The McCabe brothers leave town on the motorbike, but it soon breaks down. Stranded on the side of the road, they encounter the blonde-haired Kate, who indicates that one of the guests at her bed and breakfast suffered a seizure in a nearby meadow. After carrying the unconscious young woman to Kate’s establishment, Bill decides to make Kate the object of his conquest. Dennis reminds him that they are there to find their father. After scouring the phone book, Dennis comes up with a possible address for the mysterious “Tara.” Bill orders his brother to deal with the motorcycle, and persuades Kate to drive him around Long Island. When they arrive at the address, they find the property burned to the ground. Meanwhile, Dennis pushes the motorcycle to a gas station, and indicates that the clutch is broken. Mike, the attendant, expresses regret and returns to strumming his electric guitar. Dennis walks back to the bed and breakfast, where he meets Elina, the woman who had a seizure. Though aloof, she invites Dennis to sit and chat. However, when a red sports car pulls up outside, she ducks behind a barstool. Crouching beside her, Dennis observes a man get out of the car, only to drive away a moment later. Elina turns on Dennis, demanding to know what brought him to Long Island. Back at the fire site, Kate warns Bill that her psychotic ex-husband, Jack, has just been released from prison. She suggests that the McCabe brothers stay for a few days to allay her fears. Kate then digs up a small tree, intent on transplanting it at the bed and breakfast. Bill admires her love of nature, before kissing her. She slaps him and suggests they head back. That evening, Bill, Dennis, Kate, and Elina share an awkward dinner together. Afterward, Dennis learns that Elina has been waiting on Long Island to meet William McCabe. When he deduces that she is his father’s girl friend, he cannot help but remark on their age difference. Elina sighs. Meanwhile, Kate apologizes for slapping Bill, confessing that she would not mind if he kissed her. Having reconciled their earlier differences, the four adults spend the night drinking and socializing. They are joined by Kate’s longtime friend, Martin, who regards Bill with suspicion. When Kate falls asleep on the pool table, a drunken Martin reveals his affection for her, despite her rejections. Martin leaves and Kate awakens, wondering aloud if Bill is only out to seduce her. He claims that she has seduced him. Bill locates Dennis and announces his desire to stay on Long Island with Kate and run a tree farm. Just then, they hear a noise. Searching the property, Dennis notices that Elina is missing. He asks Kate who or what “Tara” might mean, and Kate instantly recognizes the name of Martin’s boat. At daybreak, Dennis drives to the docks to confront his father. Meanwhile, Bill and Kate have sex. Afterward, Kate slips out of bed to tend to her trees. Noticing a red car in the driveway, she alerts Bill that her ex-husband is on the premises. However, Bill discovers that Jack is not the dangerous lunatic Kate made him out to be. Kate makes breakfast for the ex-convict. Meanwhile, Dennis demands to know if his father bombed the Pentagon. William rejects the accusation, but wryly admits he has enjoyed being on the lam for twenty years. On the way back to the bed and breakfast, Dennis stops at the gas station. Mike warns him that the station owner is in no mood to discuss buying the broken motorcycle, but Dennis persists, shocked when the man pulls a gun and accuses him of stealing the bike and deceiving Kate. They call Kate to the gas station. The owner informs her that police are on their way to arrest Dennis for the stolen motorcycle, as well as for his involvement in a computer store robbery a few days ago. Kate realizes Bill is the suspect, not Dennis. She confronts her lover and suggests he leave Long Island with his father. Bill asks for her car keys, kisses her, and drives to where Martin’s boat is docked. However, at the sight of his father, he scowls and turns on his heel. Bill drives back to the bed and breakfast, prepared to turn himself in.
