After a frustrating day at work and a hollow promotion, Mark buys a lobster for dinner but can't bring himself to cook it. Seeing his own life mirrored in the creature's fate, he impulsively spends the day giving it a final taste of freedom - a park, a swim, an arcade. What begins as absurdity turns quietly profound as Mark confronts his own fear of stagnation and the need to change course. Lobster Day is a darkly funny and unexpectedly moving story about connection, compassion, and the courage to let go.
