Eleven-year-old Danny Wexler, the only Jewish boy in his blue-collar town during the late 1970s, is obsessed with the Bermuda Triangle. When a local child goes missing, Danny's convinced it's connected to an old Bermuda Triangle theory involving UFOs. With his two best friends and their Spacetron telescope, Danny heads to his backyard to investigate. But hunting for extraterrestrials is complicated, and it doesn't help that his friend Nicholas's mom doesn't want her son hanging out with a Jewish boy. Equipped with his super-secret spy notebook, Danny sets out to fight both the aliens and the growing anti-Semitism in the town, in hopes of mending his divided community.
