When Kathryn collides with Lucien Wolfe on a Vancouver street, neither knows that it will be life-changing. Kathryn's life has become mundane and, with Lucien's prompting, she and friends, Carling and Halle, decide to shake things up with a trip to Mexico.

Carling meets a "baby" sailor half her age and finds unexpected new rewards in life. Kathryn, bereaved and running on empty, discovers that life can be full again if you only open your heart to new possibilities.

While Carling and Kathryn are enriching their lives, Halle and her new partner, Lucien, take pillow talk to the extreme with a murder pact to rid their lives of problematic people. Can you go from law-abiding to murderous in just a few weeks? Halle and Lucien play the game, each intent on the deadly finish line.

As the group of friends travel the west coast from Puerto Vallarta to Vancouver on a yacht that Lucien has bought, the fallout from the Mexican trip sets each friend on a trajectory that no one saw coming.
