Or, the ultimate:
"An accident caused by Lieutenant Daniels causes Captain Archer to begin jumping back and forwards in time, his consciousness merging with the bodies of people living in each era. Now, aided only by a holographic representation of Trip Tucker, he must put right the timeline, each time hoping that the next jump - will be the jump home..."
Sorry, couldn't resist...
"That might have been the biggest mistake of my life..."
"It is unlikely. I predict there is scope for even greater mistakes in the future given your obvious talent for them."
