Las Vegas Lady(1975)

In Las Vegas, Lucky and two of her girlfriends, Carol and Lisa, plan to steal half a million dollars from the sadistic manager of the Circus Circus Casino. A shadowy man is their contact and organizer. Each of the women could be a weak link in a scheme that has to be flawless: Lucky's boyfriend is a security officer at the casino, Lisa is a trapeze artist who's now plagued with vertigo, and Carol is in debt to a nasty thug - plus, as a Black woman, she's subject to additional harassment. Can the gals pull off the heist, or is the plan, with it's mysterious organizer, too complicated to succeed?
