TWO Afghan men were found unconscious as they were trying to smuggle into Dublin on a car ferry from France.
It is believed the migrants spent 13 hours in a fridge before they were airlifted to a hospital, then were arrested by the UK Border Force.
A coastguard helicopter was scrambled to the ship which raised the alarm around 20 miles off the coast of Devon.
The distress call was sent from the ship off Start Point at 7.30pm on Sunday, after the two men were found hiding in the ferry Epsilon, operated by Irish Ferries.
Despite the alarming situation, the migrants were fairly lucky and already made a full recovery, according to the police.
Devon and Cornwall Police said: "They have been seen by medical staff and their condition is not as serious as originally thought and have made a full recovery."
It comes just a month after warning migrants are using ferries from Bilbao in Spain, after the closure of Calais Jungle.
To avoid the migrants arriving in the UK, ferry firms are fined by the UK for each stowaway who comes to Britain and they must also pay for their flights back.
The number of immigrants who have been caught this year trying to board a ferry to the UK in Bilbao is 1,251, already three times the number for the whole of 2016.
Those migrants who try to target ports are being sent to detention centres. Their number is over 100 only during September.
A group of 40 children who arrived in Portsmouth without adult supervision are also sent to a detention centre near Madrid, before being deported.
A spokesman for Brittany Ferries said: "Those who repeatedly target port facilities [in Santander] are sent to a detention centre near Madrid before being deported.
"In Bilbao, a port infraction is treated as a civil misdemeanour and offenders are simply released to try again."
A spokesperson for Irish ferries said: "The stowaways managed to evade numerous checks at the French port and had hidden themselves in a refrigerated trailer on the freight deck.
"One of our crew was alerted by one of the men trying to attract attention by banging the inside of the trailer.
"He thankfully managed to get the trailer open."
