Richard Dreyfuss plays Moses Wine, an ex-Sixties radical who pays the bills as a private eye. Wine is hired to stem a smear campaign against a popular political candidate. Gradually the plot thickens into a murder case, involving a hippie leader whose values, like Wine's, have been severely compromised over the years - and who plans to blow up a major LA freeway as a protest. Susan Anspach provides a great deal of dramatic (and sexual) tension as Wine's boss. Among the minor players are future stars Mandy Patinkin and F. Murray Abraham. The Big Fix was adapted by Roger L. Simon from his own novel.
