Florance, a reclusive and eccentric pulp romance novel aficionado, lives a dull life alone with her cats but keeps her imagination lively in her own world of romantic fantasy. When her daily monotony is suddenly interrupted by an obscene prank caller, Florance finds herself unhinged by the sudden possibility of real human connection. Mouthbreather is a humorous look at how even the most socially awkward person can express pent-up desires in the most unexpected and peculiar of ways.
