The first mission of the Enterprise-B is to take a number of reporters, Captains James T. Kirk and Montgomery Scott and Commander Pavel Chekov on a ride around the solar system. It is during this demonstration that the Enterprise-B receives a distress call from the transport Lakul which, along with the Robert Fox, is transporting El-Aurian refugees from their homeworld. Being the only ship within range, the Enterprise-B responds – despite lacking a tractor beam, photon torpedoes, and medical staff (as a running gag, all of these things were to be installed on Tuesday).
Harriman and his crew try to free the ships by a variety of means to no avail. After one of the ships is destroyed, Harriman takes Kirk's advice and takes the Enterprise-B into the rift. When the Enterprise-B gets within transporter range, Scott is able to rescue 47 out of the 150 people aboard the Lakul before its destruction. However the Enterprise-B becomes trapped in the rift. Scott believes the navigational deflector can be adapted to emit a blast that can free the ship. The reconfiguration requires manual adjustments, which Kirk performs. As the Enterprise-B moves free of the rift, an energy discharge from the rift strikes the ship near the deflector dish, shearing through several sections in the stardrive hull, including the area in which Kirk was working. With that area exposed to space, Kirk goes missing and is presumed dead.
Great piece
