The spring eel season has arrived, but coastal Maine is still plagued by winter weather. Three teams of eel fishermen, the Eelinators, the Maineiacs and the Grinders, come together to toast the start of the 10-week elver (glass eel) gold rush and reboot their rivalry. As the men approach their familiar fishing holes, they face severe challenges because frigid water temperatures do little to encourage the baby eels in their migration. The Maineiacs gamble on new territory near the ocean, and despite a run-in with rogue fishermen, they take an early lead as the gambles pay off.
