In 1964, aspiring jazz drummer Guy Patterson is working in his family's appliance store in
Erie, Pennsylvania. His friends Jimmy Mattingly II and Lenny Haise ask him to perform in their band at the local talent show, because their regular drummer broke his arm. They rehearse a song in Jimmy's garage, a slow-tempo ballad he wrote titled "
That Thing You Do!". Jimmy's girlfriend Faye Dolan, inspired by the
Beatles, suggests the band should be named "The Oneders" (pronounced "wonders"). At the talent show, Guy propels the song into a faster tempo, helping the band win the competition and earning them a paying gig at a local pizza parlor. After the Oneders decide to record the song (with production help from Guy's uncle Bob) and sell
45's of it, local talent promoter Phil Horace notices the band, promising them radio airplay within 10 days. Lenny convinces the band to sign with Phil. Phil keeps his promise and the song gets regular play on Pennsylvania radio, becoming an instant local hit. He eventually books the Oneders for a showcase concert in Pittsburgh, but technical difficulties and the band's lack of stagecraft result in a disastrous performance. Afterward, Phil introduces a dispirited Guy to Mr. White, an
A&R representative for Play-Tone Records, who offers the band a contract and becomes their manager. White renames the band "The Wonders" and unifies their style and presentation. He places them on the Play-Tone tour of Midwestern state fairs, with Faye handling their wardrobes so she can stay on the tour with Jimmy. During the tour, the Wonders meet other acts, learn about the business, and improve their performing skills. "That Thing You Do!" garners national radio airplay, raising the band's popularity and eventually reaching number 7 on the
Billboard Hot 100. Mr. White then sends them to Los Angeles for publicity, including radio and film appearances. While the rest of the band revels in their newfound fame and success, Jimmy becomes increasingly irritable due to wanting to record a new album. On the day of their appearance on
The Hollywood Television Showcase (a nationally televised live variety show), Guy is hung over after meeting his idol, jazz pianist Del Paxton, at a club the previous night. Jimmy is nervous and overcome with nausea, and Lenny is preoccupied with his new girlfriend. The band's bass guitarist is absent after abruptly joining the
Marine Corps, so Mr. White has replaced him with experienced session guitarist Scott "Wolfman" Pell. Still, the Wonders successfully perform "That Thing You Do!" on the show, but when television captions introduce the individual members, Jimmy is visibly angered by an additional caption announcing his apparent engagement. In the dressing room after the performance, Jimmy furiously accuses Faye of orchestrating the engagement announcement. Faye, already disillusioned with Jimmy's behavior, breaks up with him. Lenny, meanwhile, elopes to Las Vegas with his girlfriend. The next day, at a scheduled Play-Tone recording session, Mr. White has brought new material approved by Play-Tone for Jimmy and Guy to record, as dictated by the band's contract. Jimmy, insistent on recording his own songs, immediately quits and leaves. Guy is downcast, but Mr. White reassures him that short-lived
one-hit wonders are common in the music industry. Now left alone in the studio, Guy improvises on his drumkit, attracting the attention of Del Paxton who is there for his own recording session. Impressed by Guy's drumming, Del joins Guy and they record an improvised jazz duet. Returning to the hotel to check out, Guy tells a dejected Faye that he plans to stay in Los Angeles, while she says she will return to Erie. He pursues her and they finally admit their long-hidden feelings for each other before sharing a kiss. A picture-and-text epilogue reveals the fates of the band members. Jimmy returned to Play-Tone, formed a successful new band named the Heardsmen, and became a record producer in Los Angeles. Lenny broke up with his new girlfriend, and manages a casino in
Laughlin, Nevada. The bass guitarist (named "T.B. Player" in the credits) served two tours of duty in
Vietnam with the Marines, earning a
Purple Heart, and works in construction in
Orlando, Florida. Finally, Guy and Faye married and raised four children in
Venice, California, before moving to
Bainbridge Island, Washington and founding the
Puget Sound Conservatory of Music, where Guy teaches jazz composition. ==Cast==
