A new communications system causes problems at Cresta Cabs when Sam and Reen accidentally broadcast a private conversation to all cabs. Sam's partner Dexter returns from abroad after a breakdown caused by his unfaithful wife Tina.

Cresta Cabs is short of drivers, but Dexter has not returned to work yet. He wrongly suspects Tina of being unfaithful again and gets Cambridge to destroy an expensive painting he bought her, not realising that Cambridge is in someone else's house.

Dexter sees the insurance salesman Tina had an affair with at his house. He jumps into the Thames, and soon afterwards the insurance salesman's body is found in the boot of one of the minicabs.

Sam makes the arrangements for Dexter's funeral, but things do not go as planned. Henry drives a pregnant woman to the hospital and is mistaken for the baby's father.

Baz finally connects with one of his dates, but he learns that Andre is the father of her son. Rajiv is mugged in his minicab and is afraid to return to work. Sam asks for Rajiv's help with the company accounts and learns that Dexter embezzled large amounts of money.

Phil is promised a spot for his band in a talent show if he can acquire a boa constrictor for one of his agent's other clients. Marlon gets a job in a grocery store. Sam goes to visit his wife who is in a nursing home with early-onset Alzheimer's.

Cresta Cabs is in financial difficulties after Dexter stole money from the company. His wife Tina loses her house and shows up on Sam's doorstep, interrupting an intimate moment with Reen. Cambridge is tricked into skinny dipping by two female passengers who take his clothes and minicab.

Sam is unable to resist Tina's advances. Phil is in debt to a recording studio. He has car trouble while driving a businessman from the airport and later returns a wallet the man left in his cab.

Reen learns about Sam and Tina. Upset about Phil's debt, Chrissie takes the kids to her mother's. Phil accepts an offer to work as a driver to Mr. Eugene, the businessman whose wallet he returned. Marlon is taken advantage of by a girl and her friends.

Tina continues to insinuate herself into Sam's life. Phil realises that Chrissie has left him. Sam tries to get an important contract for Cresta Cabs, but the meeting is a disaster. Rajiv is offered a partnership in Cresta Cabs. Baz wakes up in bed with the owner of his dating agency.

Tina shows no signs of leaving Sam's house. Sam gets the important contract for Cresta Cabs and goes out to dinner with the company's owner, Helen Jackson. Marlon is tricked into letting some kids steal from the shop where he works. The owner of Baz's dating agency is shocked when he rejects her. Mr. Eugene asks Phil to deliver some packages and hire female escorts for a party.

Andre meets a young girl in a bar, and Sam goes out with Helen Jackson, but they discover that the girl is Andre's daughter with Helen. Phil brings escorts to Mr. Eugene's party where cocaine is being served.

Tina learns about Helen and moves out. Reen tells Sam she and her husband are trying to save their relationship. Sam gets caught in an explosion when Barry's mechanic brothers-in-law dump petrol down the toilet. Reen overhears Sam confessing his feelings for her. Phil is arrested and learns that he has been delivering drugs for Mr. Eugene. He agrees to wear a wire but Mr. Eugene reveals that he is untouchable because of the high-powered men who were at his party.

The Story picks up from where we last left it. The company is flourishing, but Sam is having nightmares about his old friend and business partner Dexter, who was last seen jumping off Blackfriars Bridge. His love life is still non-existent too.

Sam, who is suffering from anxiety, insomnia and nightmares, gets a phone call from his lawyer while Rajiv has probelms at home.

Sam Mountjoy has unwittingly gained a new 'lodger' and he needs help. Unfortunately, the kind of 'help' he is looking for comes in at a cool £25,000 and it's up to Sam to find it. Meanwhile, Reen's already difficult marriage takes a turn for the worse with some very unexpected consequences for everyone involved.
