Plot

In the heat of a relentless summer, Ned Racine, an inept South Florida lawyer, meets and begins an affair with Matty Walker. Matty's wealthy husband, Edmund, is always away on business during the week. Late one night, Ned arrives at the Walker mansion and, seeing Matty in the gazebo, playfully propositions her. The woman is actually Mary Ann Simpson, Matty's old high school friend who physically resembles her and who is briefly in town. Soon after, Matty tells Ned she wants a divorce, but a prenuptial agreement would leave her almost nothing. When she wishes Edmund was dead, Ned suggests murdering him so Matty can inherit his wealth. Ned consults a shady former client, Teddy Lewis, an explosives expert, who provides Ned a small incendiary device though he advises Ned to abandon his plans.
