Psihiatrinja iz New Yorka (Barbra Streisand), ki zdravi čustveno nestabilno žensko, se o družinski preteklosti pogovarja z njenim bratom dvojčkom (Nick Nolte). Nepričakovano se zbližata in nazadnje postaneta več kot le prijatelja.Nogometni trener in učitelj angleščine Tom Wingo (Nick Nolte) ima v življenju kar nekaj težav. Izgubil je službo, poleg tega pa ga vara še žena. Zato ga še toliko bolj prizadene novica, da je njegova sestra dvojčica Savannah (Melinda Dillon) skušala storiti samomor. Sestrina psihiatrinja dr. Susan Lowenstein (Barbra Streisand) ga prosi, naj pride iz Južne Karoline v New York na posvet. V dolgih pogovorih skušata odkriti vzrok za Savannihino dejanje. Med psihoanalizo se počasi bližata že davno pozabljenim dogodkom v družini Wingo, ki zadevajo tudi Tomovo življenje. Pri tem se Tom in Susan nepričakovano zbližata in nazadnje postaneta več kot le prijatelja. Ljubezenska drama "Princ plime" je resna zgodba brez trendovskega humorja in osladne romantike, ki bi gledalca odvrnili od globljega in temačnejšega pomena zgodbe. Film je prejel kar sedem nominacij za oskarja.
The Wingo family is from South Carolina, they growing up in a house on a tidal plain. The oldest offspring, Lucas, largely acted as the protector for his younger twins siblings, Tom and Savannah, in light of their dysfunctional growing up, with their shrimper father, Henry, distant and abusive if/when he did pay them any attention, and their mother, Lila, while not doting on them most concerned about appearances and striving for social standing. Now in middle age, Savannah is a New York based poet, Tom, still living on the South Carolina coast outside of Charleston with his wife Sally and their own three doting daughters, taking a break from his high school teaching/football coaching job, while Lucas has long since died while still standing up for himself and his beliefs. Lila, divorced and now remarried with that wealth and social standing she so long desired, receives news that Savannah is in the hospital following her most recent suicide attempt. Not wanting to face the blame directly as she suspects, she assigns Tom to go to New York to speak to Savannah's therapist, Susan Loewenstein, to provide any information of a family history nature that could help in Savannah's recovery. Tom agrees despite hating New York, and it being not a good time since he and Sally are experiencing marital problems, they both just knowing that things between them are not working, and not having been intimate in months. As Tom and Loewenstein (as he calls her) begin their sessions, Tom is slow to divulge the Wingo family problems to her. But he learns that she too is having her own family problems, with her concert violinist husband Herbert Woodruff being self absorbed and condescending, with their young adult son, Bernard, hating both largely because of they predestining his life also as a concert violinist. Tom and Loewenstein's sessions blossom into a friendship and romance, where their talks, in addition to helping Savannah, may help them both in dealing with their own life proble
