Thr mission begins when Ashley phones Johnny and says she is in trouble. Johnny makes his way to her house. When he arrives two of Dimitri Rascolov's men are there. They say that Ashley is in debt to Dimitri and he has not been payed. They tell Johnny that he has to kidnap Roman Bellic or they'll blow Ashley's brains out. Johnny goes out to kidnap Roman with the help of Malc.
In the mission you must drive to Malc's location. You both then get into his car. At this point you must drive to the hardware store where Roman gambles. A cutscene then begins which shows you and Malc putting Roman in the back of your car. Now you need to drive to the warehouse in Bohan and drop Roman off.
Most will recognise this mission because in GTA IV you need to rescue Roman from that warehouse
