Jonah is an aspiring actor whose career has been reduced to making lady noises for an x-rated video game.
A chance encounter with Sadie, a despondent girl with her own baggage – namely a mom who does unspeakable things for money – leads to a cross-country road trip to fulfill a 20 year old promise Jonah made to his terminally ill father. Through a poetic use of flashbacks, and interweaving timelines, Humdinger unfolds a story barreling towards a crescendo, while amplifying the emotional and fragmented state of the characters.
