Ji-Woong is unable to get a job and his allowance from his mother has just been spent.
Without even 50 won to spend on a girlfriend, he also faces eviction from his apartment.
Just then, he meets his savior, a beer bottle collector, Hong-Sil, whose philosophy on life depends much on extreme stinginess who thinks that religion, relationships and being sick are just a waste of money.
Hong-Sil offers to teach Ji-Woong the ropes to money making based on the condition that he follows whatever she asks of him, for two months.
Strangely, she makes a bank account under his name.
Ji-Woong accepts Hong-Sil's various commands and after many quarrels, business starts to pick up.
When they started out, they each had their own agendas. Will they make it in the end?
