It's 1967 and Moe Prager is wandering aimlessly through his college career and his life. All that changes when his girlfriend Mindy is viciously beaten into a coma and left to die on the snow-covered streets of Brooklyn. Suddenly, Moe has purpose. He is determined to find out who's done this to Mindy and why. But Mindy is not the only person in Moe's life who's in danger. Someone is also trying to kill his best and oldest friend, Bobby Friedman.
Things get really strange when Moe enlists the aid of Lids, a half-cracked genius drug pusher from the old neighborhood. Lids hooks Moe up with his first solid information. Problem is, the info seems to take Moe in five directions at once and leads to more questions than answers. How is a bitter old camp survivor connected to the dead man in the apartment above his fixit shop, or to the OD-ed junkie found on the boardwalk in Coney Island? What could an underground radical group have to do with the local Mafioso capo? And where do Mindy and Bobby fit into any of this?
Moe will risk everything to find the answers. He will travel from the pot-holed pavement of Brighton Beach to the Pocono Mountains to the runways at Kennedy Airport. But no matter how far he goes or how fast he gets there, all roads lead to Onion Street.
