Heard this one?

US marshals hunt you for a murder you didn’t commit. You pursue the one-armed man who killed your wife, but the problem is you’ve become a zombie, which seriously slows you down. You are Zombie Fugitive.

The twist: the one-armed man tears off * your* arm – now making the case against you rock solid – but you bite him and turn him into a zombie as well.

The climax is a rooftop zombie slap fest.
