Casey inexplicably wakes up one morning with a second dick. Though he wants nothing more than to have it removed, his girlfriend, Sasha, sees it as a miracle he should want to keep.

In a small NYC apartment, Maggie, independent to a fault, is caught off guard when her obnoxiously reasonable boyfriend asks her to move in with him. Rather than deal with the question, Maggie becomes determined to discover the source of an increasingly strong and mysterious smell from next door. What she finds brings her face to face with an impossible-to-ignore example of what’s at stake if she refuses to abandon her stale but comfortable life.
