As of August 2015, there is no plot of “Eddie and the Cruisers III,” as there has not been a third installment in the “Eddie and the Cruisers” movie series. Any news of “Eddie and the Cruisers III” is a hoax or a rumor.
A 1983 film, “Eddie and the Cruisers” is a beloved cult classic about Eddie Wilson, a fictitious rock star, and his band Eddie and the Cruisers. It was directed by Martin Davidson and starred Michael Paré, Joe Pantoliano, Ellen Barkin and Tom Berenger in the lead roles with Paré playing Eddie Wilson. The film is based on P.F. Kluge’s novel by the same name.
The film received negative and mixed reviews from critics and flopped at the box office. It was rediscovered after a pay cable run on HBO and was rereleased in 1984. The film failed again at the box office but has since attained cult status.
The screenings on HBO resulted in increased popularity of the soundtrack, which resulted in the rerelease of the soundtrack in 1984. The song “On the Dark Side” topped the charts on Billboard's Mainstream, Rock and Heatseeker charts.
A sequel, “Eddie and the Cruisers II: Eddie Lives!” was released in 1989. Davidson refused to be associated with the film. Paré returned to play the role of Eddie Wilson and was the only star from the original in the sequel.
