Captain's log - Stardate 2261.286

We have received a transmission from the Klingon Empire requesting that we give assistance in pursuit of an unidentified vessel that has fled from their territory into Imperial Starfleet space. I have agreed to intercept the ship and the Klingon Commander of the Seg'pa sent the coordinates of where the vessel entered our space as well as what details they were able to get from the intruder.

Sounds like an older small class cargo ship with illegal modifications. Possibly a pirate. If so, they will find they're playing in the wrong backyard.
