It is the year 2070, and the Mars Colony operates with 30,000 inhabitants. But today something has gone terribly wrong. A "Death Droid" (D 1075) has gone offline, dysfunctional, and is destroying things. Mars first, official serial killer is leaving a body count everywhere. And in the Mars Far Desert, there is detection of a strange and invisible alien. Not much time for ISP Detective David Ward and the ISP to solve the case!!
