Here's the Plot Summary:
"An unmarried 40-year-old woman turns to a turkey baster in order to become pregnant. Seven years later, she reunites with her best friend, who has been living with a secret: he replaced her preferred sperm sample with his own.
Kassie (Jennifer Aniston) and Wally (Jason Bateman) are best friends. Being unlucky in love, Kassie has decided to have a child using artificial insemination. Wally doesn't like this idea, but he isn't capable of admitting to himself, let alone to Kassie, that he's in love with her. At Kassie's artificial insemination party, Wally gets very drunk and spies the sperm donor's sample in the bathroom. Wally was way too drunk to know what he did that night, and Kassie has moved away because she doesn't feel that New York City is a place to raise a child. Now 7 years later, Kassie has moved back with her son Sebastian. While she is looking to get Roland (the sperm donor) more involved in their lives, Wally can't help but notice the many striking similarities that he and Sebastian share."
Synopsis: JENNIFER ANISTON stars alongside JASON BATEMAN in this offbeat comedy as Kassie, a smart, fun—loving single woman who, despite her neurotic best friend Wally’s (BATEMAN) objections, decides it’s time to have a baby—even if it means doing it by herself… with a little help from a charming sperm donor (PATRICK WILSON). But, unbeknownst to her, Kassie’s plans go awry because of a last—minute switch that isn’t discovered until seven years later when Wally finally gets acquainted with Kassie’s cute—though slightly neurotic—son. From the people behind “Little Miss Sunshine” and “Juno” comes “The Switch,” due in theaters this summer.
Hmm, Roland's fluid! Wally gonna hijack Kassie's pregnancy!
The inebriated prankster proceeds to replace it with his own sample, while getting in the mood to do so by admiring a perky photo of—I kid you not—Diane Sawyer on the cover of a magazine.
Watch the trailer and get some idea on what is THE SWITCH all about!
