A Japan-set battle-royale comedy over a vial of sperm is centered around three women on the verge of a nervous breakdown from hearing their biological clock ticking away; a doctor and manager of a sperm bank Sana Kobayashi, a single-mother Maron Kuribayashi, and an alluring receptionist Mayumi Kujyo. Unknowingly, the three shared a beloved partner and a sperm donor, Makoto, but lost him in a sudden accident. The night of Makoto’s funeral they are shocked to discover each other in hisroom. In a rage of screaming, thrashing, and boasting about their own sexual prowess with Makoto, more fierce emotions erupt once Sana’s plan to self-inseminate is exposed, but this leads to unexpected consequences. They affirm their real love for Makoto and reveal his true wishes.
