Diggers is a film about four clam diggers on Long Island in 1976. Hunt (Paul Rudd), Lozo (Ken Marino), Jack (Ron Eldard), and Cons (Josh Hamilton) are struggling as the bay is being taken away from them by a corporate clamming outfit.
Each of them has their own struggles and distractions - Hunt is an amateur photographer, Cons deals drugs, Jack is a womanizer, and Lozo focuses on procreating with his wife, Sarah Paulson.
Their lives take a turn when Hunt's father passes away, who had worked hard on the bay to make a living. After the funeral, Hunt starts spending time with Zoey (Lauren Ambrose), a wealthy girl from the city who is exploring life out east. Meanwhile, Hunt's sister Gina (Maura Tierney) gets involved with Jack.
After a night in jail following a bar fight, the four friends decide to make changes in their lives. They give Hunt's father a proper funeral, Lozo gets a real job, and Hunt decides to chase his dream of becoming a professional photographer by heading west to be with Zoey.
