Shameless Season 5 (2008)

A drunken call of nature on a generator turns just another night out for Frank into a nightmare.
At hospital he's told that tests show he has a heart condition and may not make it to the weekend.
With these words ringing in his ears, he sets out to drink and drug himself into a stupor, only to be visited by his younger self and challenged to answer the question: "What is the point of Frank Gallagher?"
On one of his regular trips home from university, a little bit of Lip's other life makes an unwelcome appearance in Chatsworth, throwing Mandy into uproar and culminating in a knock-down, drag-out fight in The Jockey with shocking consequences.
Elsewhere on the estate, Lillian proves to be quite the madame when she settles on an unconventional way to turn her spare rooms into a little extra cash.
