In a small and picturesque town, a young veterinarian named Leo faces the biggest crisis of his life. After the death of his beloved dog, he finds an ancient magical collar in his clinic that, against all odds, grants him the ability to revive his pet. However, there is a catch: every time he uses the power of the collar, he becomes trapped in a cycle of life and death, losing a part of himself each time an animal is brought back to life.
As Leo experiences the ups and downs of this new life, he begins to use the collar to save other animals in the town, becoming a local hero. But things get complicated when he discovers that he can not only revive animals; some lost souls of humans are also drawn to the power of the collar. With the help of his sister, Ana, who is skeptical of magic but has always supported him, Leo must learn to balance his selfish desires with the responsibility that comes with his gift.
As the resurrections become more complicated and he starts to lose his own essence, Leo faces a great decision: should he continue to play God or accept the harsh reality of life and death? This touching story explores love, sacrifice, and the light that shines in the darkness as Leo embarks on an emotional journey that will change his life forever.
