When Eric's former love, Christine, moves back to town after a twenty-year absence (with a ten-year-old daughter, who may or may not be Eric 's) his greatest desire is to find a way back into her heart. Should he start by asking his much younger girlfriend to move out, or will her presence make Christine jealous enough to want him back? (helluva sperm delivery system ol Eric has there if it took 10 years to reach the egg)
Before Eric can do anything on the romantic front, a crisis looms: dead seals begin washing up on the area's beaches. Have they been poisoned by disgruntled fishermen or stricken by a mysterious ailment? As the local marine mammal expert, Eric is called in to discover the cause of the epidemic. Solving the mystery will boost his sagging career and prevent the college Dean from sending him to academic purgatory.
Eric can't concentrate on the seal crisis, however. The only thing he can think about is winning Christine back. But Christine has no time for romance. She is busy raising her daughter and working with an immigrants' rights group. To complicate matters further, Eric must bridge the twenty-year divide without mentioning the incident that precipitated Christine's departure: the accidental death of a logger, killed by a group of eco-activists with whom Eric and Christine were once involved.
