One of Harry Rawlins' robberies goes wrong, resulting in the deaths of three of the robbers. Dolly is given some keys by Harry's cousin Eddie at Harry's funeral. The police begin a search for Harry's ledgers, in which he kept all his notes on past and future robberies, as do the Fisher brothers, who were rivals. Dolly finds the ledgers, along with a gun and money, in a Harry's deposit box at the bank. The police follow Dolly around, but she gives them the slip a few times to meet up with Shirley and Linda, whose husbands also died in the explosion. They decide to carry out the robbery themselves. When Dolly returns home, she finds her house in a mess and someone in the living room.

Dolly finds Boxer Davis, who is working for the Fisher brothers, in her house when she returns home. Shirley and Linda find cars to use, but neither vehicle seems to be much good. Linda goes to a garage to get it fixed and meets the owner, Carlos, who she begins a relationship with, much to Dolly's disgust. While Linda is at work, she bumps into an old friend, Bella, to whom she tells everything, and subsequently takes her to the headquarters, calling Dolly and Shirley to go there, but it takes a while to persuade Dolly to let Bella in.

Dolly has told Boxer Davis that Harry is still alive to try to keep the Fisher brothers off their backs. Tony Fisher visits Eddie and tells him what Boxer Davis has been telling them. Later, Eddie visits Boxer and takes him out and gets him drunk, and then leaves him in a back alley - where a mysterious driver runs him down. Dolly, Linda, Bella and Shirley go up to the mountains to practise for the robbery - and an unexpected face returns from the dead.

Linda and Bella have an argument, and it is overheard by Bella's fiance and he hears everything about her past. Dolly receives a letter telling her about Harry, and she rushes to hide the money somewhere else. Harry arranges his return to England, as do Bella, Linda and Shirley. Harry is met by Mickey at the airport, who he tells to follow Linda and Bella. Harry then gets someone to go to them to find out where Dolly is, but he misses Linda and beats up the woman who is staying at Bella's. The widows meet up and decide to tell Harry that they are going to make a deal and give him £60,000 to leave them alone for good, but they secretly have decided to call the police when they have given Harry the money.

Dolly, Bella, Shirley and Linda meet to go over the plan for the handover. Linda makes a dummy to use in her car and Micky fixes it for Shirley to join a modeling company. Shirley's mother tells her that she is pregnant, which takes Shirley's mind off the plan. Linda leaves and gets a gun, which Dolly has ordered her not to do. Dolly phones Harry and tells him where to meet her. When she is about to hand over the money, Linda and Bella arrive late and Harry rushes to leave, running Linda over and killing her. When Dolly finds out that Harry has killed Linda, she goes to his old house with the gun, but he isn't there. The P.I., Vic Morgan, arrives and finds her standing outside with the gun.

Vic Morgan goes to see D.I. Resnick at the hospital and tells him what he has found out so far. Bella tells Shirley that Linda is dead. Dolly and Bella find out that Harry is going to do another robbery when they go to the hideout to look for Dolly's book. Bella rents the lockup next door to keep an eye on how the robbery plan is progressing. Harry and Micky pay a visit to Arnie Fisher and get ""permission"" to use his club for a party. Morgan visits Dolly and asks her out to lunch and overhears her crying. The police catch up with Sunny, the fence for the money.

Dolly and Bella go to the lockup and find out that the robbery will be carried out earlier than they thought. They rush to phone the police and race to the club, but they are already there. They go in and hold up the staff and the models and take the jewellery. Shirley gets shot by Micky and he makes a run for it, but Dolly and Bella follow him and he is injured in a collision with a lorry - and is later shot by Harry. Bella leaves the country for Los Angeles and Dolly hides the diamonds, but she's also got a surprise in store for Harry.
