Tom is 15 years old. He's staying at his father’s house for the weekend, to spend an oppressive father-and-son moment under the looming shadow of a deceased brother. However, Tom has come with a bottle of Bluestar, a product that exposes blood trails. With his friend Kevin, he wants to visit an abandoned house at night, the one in which a man killed his entire family. This ghastly escapade will take an unexpected turn for Tom: the Bluestar has something to reveal to him.
