Rickards told TV Guide that the instalment, which is similar to The Hangover, will see Jenna going to a party.
"You get to see Jenna really out of control and then picking up the pieces immediately afterwards," Rickards teased.
"Normally she's got this old soul personality where she's able to figure things out and handle them... but this time she is incapable. She does something I don't think anybody would expect her to do and it ends up costing her."
Rickards also promised that several questions will be answered before the end of the season, explaining that Jenna will choose between Matty and Jake and the author of the mysterious letter will be revealed.
She added: "A few bridges are burned between Jenna and characters you wouldn't expect."
Awkward, which has already been renewed for a second season, airs on Tuesdays at 11/10c on MTV. The show will begin in the UK tonight at 10pm on MTV.
