One day Ginny wakes up and whenever she opens her mouth, right behind her teeth there’s a portal to another dimension. This dimension is very similar to our dimension, except in the Ginny’s mouth dimension the Nazi’s won World War II(!). One night, while Ginny is snoring with her mouth open (and thus opening the portal to the other dimension), a soldier from Ginny’s alternate mouth dimension finds the portal and pleads for Ginny’s help. The soldier is part of an underground resistance that is not nearly as anti-Semitic as the Nazi’s. The movement is attempting to overthrow the Nazi government, but needs help. They need plans for a nuclear bomb, something that was not invented in his alternate dimension.
Ginny works on finding out how to make a nuclear bomb while the soldier’s situation becomes more and more desperate. When she finally finds the plans and opens her mouth and puts them through her mouth portal, the soldier is dismayed because he doesn’t have access to some of the nuclear bomb ingredients. Ginny agrees to help him find these too. But time is short for Ginny. With the portal opening in her mouth, she is unable to eat as all the food she consumes goes into the mouth dimension rather than her stomach. She’s wasting away, hungrier and thirstier than we can possibly imagine.
Meanwhile, the soldier and Ginny start to fall in love. As he shouts his proclamation of love through Ginny’s mouth’s portal hole, Ginny weeps because not only is she hungry and thirsty and having a hard time finding the radioactive ingredients she needs to shove into her mouth/portal, but she’s also in love with the soldier and she knows they can never truly be together because he can’t fit through her mouth.
Close to dying of dehydration, Ginny finds the needed parts of the nuclear bomb and she’s able to swallow them into her mouth portal. But getting them has attracted the attention of the FBI, and she doesn’t have the strength to resist capture. As Ginny is taken away, the soldier from the alternate dimension hands off the bomb blueprints to the underground resistance leaders.
In FBI captivity Ginny is hooked up to an IV and saved from dehydration. Meanwhile, in Ginny’s mouth portal’s alternate dimension, the underground resistance completes the construction of the nuclear bomb. The soldier tells Ginny that the bomb has been deployed on
Ginny tells her FBI guard that she has a sore throat. But when he comes up to examine it, she opens her mouth and through her mouth portal the soldier shoots the FBI guard in the brain. Ginny quickly takes the guard’s keys, grabs her IV bag, and hightails it on out of there. Running with her mouth open, the soldier shoots everyone that gets in her way. Soon she has her freedom, but what about her love?
Ginny is a hero in her mouth portal’s dimension, but she’s a killer skirt in her own. Ginny and the soldier decide that they can make it work though, and they both high a minister to marry them. Ginny puts her hand down her throat and into the other dimension and the soldier puts a ring on it. The soldier puts his hand through the portal and though Ginny gags, she is able to put a ring on his finger as well. The two are married, though they can never be truly together. And though the wedding is bittersweet, the couple is happy. Together, Ginny and the Soldier have overcome so much.
But nobody can hide forever. And simultaneously the Nazi’s find the soldier and the FBI find Ginny. Both Ginny and the soldier are gunned down, and they die together, the soldier with his hand through the portal, and Ginny with her hand down her throat. The screen goes black and the words “And so the movie is a tragedy” fade in and then out of the screen. Credits.
