A lecherous old tycoon passes away leaving his estate to his much younger wife and son. A beautiful psychologist has an unusual experiment underway to study criminal tendencies which involves a priceless Ming vase. A new heir pops up!
Synopsis:Turnabout is a 100 minute farce which centers on a sporting goods company. The founder, Hiram, has passed away at age 96 leaving management of his struggling business to his son, Jason. Jason, who has been intimidated by his powerful father all his life, has not moved into the CEO's suite. The promiscuous Hiram has had many affairs but finally married late in life to Louisa. Louisa does not work at the sporting goods company but is named as controller. She has the same number of shares as Jason. Although they live under the same roof, Louisa and Jason do not get on well together - this is possibly because Jason is not Louisa's child. Hiram, perhaps sensing a future problem between Jason and Louisa, has kept 10 shares in reserve.
Carmel, a lawyer, has taken a job as an administrative assistant in the sporting goods company. She is also one of Hiram's children but must prove it to get part of the huge inheritance - no one knows this but her. Carmel has a crush on Jason. Carmel buses to work and a sleazy man attempts to rape her but she zaps him with a stun gun sending him to hospital. A bystander takes the part of the sleazy man and Carmel is sent to jail for assault.
Darryl, his marketing director and friend, has convinced him to attend the fitness center on the pretext of monitoring his product line but really he is encouraging his boss to meet "chicks".
Ruth, a psychologist, is carrying out a field test for an oriental pharmaceutical company to see the effects of a new drug on straightening out criminal tendencies - Neil, a habitual criminal, is her subject. Ruth and Neil steal an oriental antique and Ruth takes refuge in the fitness center while Neil dumps the car. Jason meets Ruth at the fitness center and is instantly attracted to her.
On a visit to the Louisa and Jason's home, Darryl is vamped by Louisa and initially is cautious about forming a relationship but eventually gives in to the scheming Louisa who needs to have a spy within the sporting goods company to protect her interests. Darryl provides Louisa with a number of company documents. Jason tries to fire Darryl but Louisa promotes him. He moves into Hiram's old office. Jason moves out of his mother's home into his own apartment. Carmel is kicked out of her lodgings but Jason, believing her to be his sister, convinces her to move in with him.
Louisa, with Darryl's help, has collected the documents she needs and brings a lawsuit against Jason to take away his shares based on the fact a DNA test had shown Jason is not Hiram's son. She is also petitioning for the 10 reserve shares which will give her undisputed control of the company. Jason has turned around company fortunes and everything is now in the black - his employees respect and even love him.
It turns out that another will is found leaving everything to Carmel. The issue of whether Carmel and Jason are siblings is resolved by DNA - they are not brother and sister. Jason asks Carmel to marry him so ownership and management issues of the sporting goods company are settled. Jason and Carmel initially fire Darryl but then hire him back in his old job as sales and marketing director.
Ruth is kicked out of the Society of Psychologists for unethical practices. She is charged by the police with a number of criminal infractions.
