Cattle Call follow the three male protagonists as they hold a fake casting call in Hollywood for a fictional independent film entitled Perfect for Me with the hope of meeting women. Richie is looking for a relationship, while Sherman and Glenn are more interested in sex. After going on dates with the girls, they eventually chose three women to be in their 'film' - Marina, Laurel and Nikita.
When Marina checks Richie's computer to find a dating site called Perfect for Me, he feels guilty and reveals to her that the whole thing was set up for the three men to find women. She storms out of his house and meets up with the other two girls at the empty 'casting studio'. It turns out that one of the other women isn't really an actress at all, and is investigating the three guys following complaints on the internet that the casting was a scam.
The girls ask to have a first read through audition of the 'script' (a translation of an old foreign language film that the guys had seen) and then tell the guys that they want to make the script 'sexier' and that they want to have lots of sex with the three producers to practice. The women set up a hotel room with cameras, and film Sherman and Glen preparing to have sex with them - Richie refuses and leaves. They then send in two masculine women with whips and sex toys instead, and then the police burst in and arrest Sherman and Glen.
After a night in jail, the two go to court facing 10-15 years ...
