When
James "Sonny" Crockett (
Don Johnson) and
Ricardo Tubbs (
Philip Michael Thomas) arrest a small-time drug dealer, they receive a visit at the police station from a man Crockett recognizes as retired
Vice squad officer Hank Weldon (
Bruce McGill). Weldon informs the pair that the man they have arrested works for a
drug lord called Tony Arcaro, who disappeared five years earlier, after narrowly avoiding a conviction. Suspicious of Weldon's motives, and his seemingly unstable mental condition, Crockett and Tubbs visit his former police partner Marty Lang (
David Strathairn), who informs them that Weldon was discharged on medical grounds rather than having retired. He had painstakingly built up a case against Arcaro and suffered a breakdown when the drug lord walked free on a technicality. When the pair leave, they find that Weldon has followed them, and is both defensive and furious concerning their visit to his partner. However, he reveals that Arcaro's successor, Freddie Constanza, is to be killed that day on Arcaro's orders. All three reach the location of the hit in time to witness Constanza's murder, and Weldon is arrested on suspicion of involvement. Weldon is later released uncharged, and acting on information he overheard from his cell-mate, tips off Crockett and Tubbs to the location of a drug deal involving Arcaro's men. When the deal is interrupted and Arcaro found to be absent, Weldon is enraged and storms off. That night, Weldon places a call to the police station claiming he has found Arcaro. When Crockett and Tubbs arrive at the scene, an abandoned tenement building, they find a disturbed but lucid Weldon, who begins to tear down a plaster wall.
Immured inside the wall is the corpse of Tony Arcaro and a newspaper from the day of his acquittal. Weldon acknowledges having killed Arcaro in response to the court trial, while Lang confesses to helping build the wall—to help his partner, flatly stating "He was my partner; you understand?" to Crockett, who confirms that he does. ==Production==
