Plot

Melinda and Vic Van Allen live with their young daughter Trixie in Little Wesley, Louisiana. Vic has retired early after developing guidance chips for combat drones, and his complicated relationship with Melinda is held together by a precarious arrangement: they sleep apart and Melinda takes lovers openly, even in their family home, while Vic finds solace in raising his large collection of snails. Their open marriage is no secret to their concerned friends, and Vic grows increasingly jealous, while Melinda laments his lack of passion.
