An independent private security firm arrives at a middle-class neighborhood in Recife, Brazil.
Bianca, a 20-year-old girl, has a device on her arm that counts down the seconds until the day she dies. In the last 15 days of her life, she has to deal with missing her family and the presence of emptiness in her home.
Miguel and his friend build what could be the first time machine. The device is designed to send a small object a few minutes into the future—but before the final test, another object unexpectedly arrives from the future. The two young scientists disagree and must face the dilemma of whether to send the artifact back or keep it in the present, in order to prevent a quantum and personal catastrophe.
