The Unified Research Facility was supposed to be the end of the threat. They split the labs into one lab per latex strain after the URF had every strain escape. They built the counters in the new labs. They thought they had the sentient latex under control. They were wrong.

Three years later, in a sub-level observation suite, the lights went out for exactly five minutes. It was long enough. The systems are shredded, the chemical counters are sabotaged, and something has sloughed off its original form to wear the face of your colleague.

You are trapped in a lockdown with two men. One is your partner. The other is a biological lie.
