On shakes terms, Quinn and Hobbs hatch a plan, exploiting a weakness in the new camera security system.

However, Hobbs manages to lift every single diamond from the vault, almost two tons worth, and by way of a proxy, holds them for a ransom of 100 million pounds.

The head of the insurance syndicate from King's Row is forced to pay the ransom, leaving him financially ruined.

Quinn seeks to avoid capture and jail by giving the diamonds back but Hobbs refuses to negotiate.

Hobbs confesses he has no interest in the diamonds or the money and wants to ruin the head of the insurance syndicate whose deliberate delay in covering his wife's medical expenses resulted in her death many years before.

Hobbs apologized for involving her, saying that he had needed a disgruntled employee for access to the diamond vault, and as compensation gave her the ransom money.

Quinn details how she spent the rest of her life donating all the unspent money to different organizations and people in need.

The website's critics consensus reads: "Michael Caine's excellent performance makes Flawless something more than an average heist movie.
