On his twenty-fifth birthday, Diesel Lagerford is visited by a
twenty-six-year-old version of himself. His look-alike spins impossible
tales of their shared future, claiming they have dozens of “brothers”
from parallel timelines who can visit each other using a T-box, a
machine they bankroll with lottery winnings. He introduces Diesel to the
incredible Lilah Spencer, the T-box operator, and Diesel falls
head-over-heels in love. But during his travels across timelines, Diesel
learns that Lilah will soon die under suspicious circumstances.
Devastated, he joins his brothers in a race to save her. Can they solve
the mystery of her death before it’s too late? And will their unusual
solution play out over time in the ways they had anticipated?
