One Good Cop  (1991)

Theatrical Release Information:
One Good Cop

An honest man struggles to do the right thing, even if it means breaking the law, in this drama. Artie Lewis (Michael Keaton) is a scrupulously ethical cop who believes in his work, loves his wife Rita (Rene Russo), and stands by his partner Stevie Diroma (Anthony LaPaglia). Stevie is a single parent, and when he's shot and killed on duty, his three daughters (Grace Johnston, Rhea Silver-Smith, and Blair Swanson) are left with nowhere to go. Artie and Rita want to adopt Stevie's girls, but Child Welfare Services decides that their apartment is too small for three children. Artie needs to buy a house, which would require a $25,000 down payment that he doesn't have. Desperate, Artie grabs his gun and robs Beniamino (Tony Plana), a particularly scummy drug dealer who was peripherally involved in Stevie's death. Artie uses most of the take to buy the house, and he gives the rest to Father Wills (Vondie Curtis-Hall), who runs a local orphanage. However, what Artie doesn't know is that Beniamino's girlfriend Grace (Rachel Ticotin) is actually an undercover cop who won't stand by as Artie plays Robin Hood. ~ Mark Deming, All Movie Guide
