Frustrated teenage boys are apt to dream up elaborate fantasies about gaining all the power they don’t have. The dream factory that is cinema has now enabled the sibling filmmakers Jonathan and Josh Baker to bring one such fancy to the screen. In “Kin,” Eli (Myles Truitt), the 14-year-old adopted son of the hard-working Man of Integrity Hal (Dennis Quaid, seemingly angling to play Harrison Ford’s younger brother in a future film), finds an unusual weapon in an abandoned warehouse.

Is it from space? From the future? Whatever it is, it can blow holes through walls. Because Eli’s a good kid, he doesn’t go vengeful. He’s instead swept up on a road trip with his bad-boy older brother Jimmy (Jack Reynor, eager to answer any “get me a Chris Pratt-type” call) who’s reneged on a $60,000 debt to some thugs.
