This isn't Disney's Little Mermaid. This Fearnet short puts a grotesque, modern twist on the legend of the Mermaid.
"Deep in a barren, fantastical wasteland lays a dilapidated circus tent. Inside, an ominous ringmaster forces his prized act, a real live mermaid to perform for a group of grimy, working class spectators. The mermaid, though frightening, is but a lovesick, caged animal praying for release from her endless torture. Unwilling to surrender his meal ticket, the ringmaster rejects her pleas for compassion and continues to confine the mermaid to her stagnant holding tank. With nowhere to escape to, the mermaid must make the choice between holding on to the hope of freedom and putting an end to her abuse."
