In the long days of summer in a beach town on the New Jersey shore, high schooler Alan (Keean Johnson) and his friends Red (Alex Neustaedter) and Smitty (Daniel Zolghadri) break into vacation homes to steal valuables, funding dates at the boardwalk and lunches at the burger stand. When Alan and his younger brother Peter (Jaeden Martell) find a bag of gold coins, they try to hide them from the others — but Red, suspicious and violently unpredictable, seems willing to do anything to get the money.
