Andre Cobb hopes his luck is finally turning around. After being sick for as long as he can remember, he's finally gotten a liver transplant. But days after the operation, he feels shaky and ill, passes out, and wakes up in a different time. He soon realizes he's slipped through time, back to the 1960s. There he meets, Michael, who Andre feels an instant connection with.

But just as suddenly as he arrived, Andre slips back to present-day Boston. As he tries to figure out if he's losing his mind, the family of his donor reaches out to let him know his new liver may have side effects... of the time travel variety. They task their youngest son, Blake, with the job of helping Andre figure out the ins and outs of time travel. As the two work together, they also grow closer.

Torn between two boys, one in the past and one in the present, Andre has to figure out where he belongs. And the more he time travels, the more he learns about himself and just how far we have and haven't come.
