Los Angeles, 3036 A.D. Humans are on the verge of extinction and the world is now run by... Trash. Tuna Tartare is a bombastic can of tuna fish who runs Throats karaoke bar with her BFF Susan, a fake Louis Vuitton purse with crippling anxiety. Upon hearing of the death of the last surviving human, Tuna is reminded of an old brush with fame that ended in embarrassment, sending her on an internal journey to battle her own insecurities and build herself back up again to do what she does best: karaoke.
