Jack Rubin is a police officer. He is dismissed after five years, accused of accepting bribes. He sets up in business as a private investigator and soon finds that his main occupation is to collect bad debts and harass vulnerable losers. However, his luck seems to turn when he takes on Mohammed Ali Malik, a Pakistani, as his partner.
Rubin, an atheist from a Jewish family, is a totally amoral tough guy and womaniser, and Malik, a Muslim and family man, loyal, frightened of his own shadow, are chalk and cheese. Yet, in spite of deep differences, their partnership seems to succeed. They have agreed one rule: never to discuss religion - and always to make their own tea and coffee.
