[2] The story is about a love potion, that enables a person to make people of the opposite sex become completely infatuated with them by simply talking.

After reading his palm and seeing absolutely no romance in his life, Ruth opens a large bottle containing a thick liquid she calls Love Potion No.

Around this time, Paul's friends buy him the services of sex worker named Marisa, but all they do is talk.

Meanwhile, Diane is having her own romantic issues, being very self-conscious about her homely appearance and only receiving physical affection from repeat one-night stands with a cruel acquaintance named Gary.

After analyzing the potion, they learn the "scientific" properties of it, which causes anyone who drinks it to attract members of the opposite sex with their voice for a period of four hours.

After analyzing it, they decide to use themselves as human test subjects, dividing the remaining potion into spray bottles.

Diane uses the potion to improve her life and ends up attracting an Italian car mogul and the prince of England, as well as getting a makeover in the process.

He meets with Diane and attempts to confess his feelings until Gary calls her on her cell phone and instructs her to never see Paul again.

Diane tells Paul she can't see him anymore and leaves, breaking his heart.

He returns to Madame Ruth and confirms that somebody looking like Gary has purchased the entire bottle of love potion No.

Marissa running screaming through the streets causes every man within ear shot to chase after her, giving Paul the opportunity to escape the police.

It is explained: When swallowed it affects the vocal cords directly so that when you speak micro-tremors encoded within your voice stimulate tiny little hairs in the inner ear of the opposite sex.

The hair vibrates, sending a signal along a nerve to the brain, which in turn produces a combination of mood-altering, endogenous chemicals responsible for the biochemical process of falling in love.

[3] Emanuel Levy of Variety called it "a light-hearted one-joke romantic comedy" and that it "tries too hard to be cute.

Glib humor and emphasis on "feel good" values aim squarely at the dating crowd and twenty-something couples.

But lack of real wit and comic vitality, absence of star names and sluggish pace make pic less appealing than it might have been.
