The movie follows four teenage girls during a summer in which each goes through a crucial life experience. They succeed due to their loyal support of each other, symbolized by a pair of jeans (the "Travelling Pants") that they take turns wearing.

Shy Lena visits European relatives on an picturesque Greek island. She falls in love with a sensitive boy in spite of the fact that their families are having an old-fashioned feud. She learns to assert herself and finally wins the family's permission for a final meeting with her lover.

Brash Bridget, an athlete, goes to sports camp and is attracted to one of the coaches. He returns her love but is more concerned with keeping his job, which he will lose if they are caught. Bridget pursues him anyway and persuades him to make love to her on a beach. He panics and breaks off the relationship, and she realizes that she has thrown away her virginity for nothing (The sexual contact is off-screen and implied, rather than stated as a fact.).

Tibby, a sour-tempered girl, decides to make a "suckumentary" with her video tools, expressing her view of the world. During the summer she befriends Bailey, a girl who turns out to be dying from leukemia. After Bailey's death, Tibby is as bitter at life as ever, but discovers that Bailey left behind a video message, thanking Tibby for her friendship and urging her not to let Bailey's tragedy blight her life.

Carmen, an emotional girl with low self-esteem, visits her estranged father and discovers that he is marrying a divorcee with teenagers of her own. Although they are blandly polite, Carmen feels like an outsider and suspects that they resent her "intrusion", and so she finally turns home. The Sisterhood urge her to attend the wedding anyway, loaning her the "magic" jeans and coming along for moral support. Her father spots her in the audience and invites her to stand with him at the altar as he marries, and she feels accepted after all.
