About Teresa[]
Teresa is the lover of feared local mafia boss Don Geno Frascotti (Mike Genovese) in 1965 Brooklyn, NY. Sam, who finds that he's leaped into Frankie La Palma (Page Moseley), an underling of the boss, who's been carrying on a hot affair with Teresa behind Geno's back, must avoid the wrath of Geno, while also following Ziggy's instructions, who has formulated a theory to help retrieve him by having Sam, as Frankie, tell Geno "what he wants to hear" that his affair with Teresa was his father's Tony's idea to send him to the salon to meet with Teresa.
Later in Geno's attic, Teresa and Sam, or Frankie, are making out while a power outage, which was caused by Frankie's brothers Primo and Segundo La Palma, who drove to Buffalo, which eventually would spread across the entire East Coast, spreads in the neighborhood. Uncomfortable about lying, he admits to her that he is not the same Frankie she knows. Teresa says it doesn't matter if he lies; she is used to men lying to her. Sam tells her she is special and deserves better as they begin to kiss, until Geno arrives and holds them at gunpoint.
Sam takes responsibility for the affair, telling Geno he insisted on bringing Teresa to the attic, despite her refusal. Geno replies that he respects a man who faces his death with honesty. Teresa intercedes and tells Geno she was the one who wanted to come to the attic. As Geno is about to shoot them, the power outage suddenly reaches his home and knocks out the lights. Sam uses the distraction to grab Geno's gun, and the two wrestle for control. As they do so, Sam suddenly leaps out of Frankie and into Don Geno. Suffering amnesia, the real Frankie appears, and upon seeing Sam/Geno he pleads their innocence.
Sam, now as Geno, has an idea of what his mission is: to keep Frankie and Teresa together as he asks the both of them if they love one another, as they both confess that they do, and they, being Teresa and the real Frankie, is granted Geno's blessing, as Sam, now as Geno announces their upcoming nuptials publicly at the neighborhood parish, before Sam leaps.
