Hey Marina,
Sorry, but is this one camera file, or multiple camera files?
EDIT: Sorry, forgot the most obvious one, which is to check an earlier version of your project if it exists in the AUTO-SAVE folder.
Obviously, depending on the length involved, it might be faster to “N” Ripple Edit (Trim for all other systems) and drag the edit point until the whole clip is visible.
You could also “F” Match Frame the first in-point, then set an outpoint in the viewer, and insert or over write back to Sequence.
Another “dirty” favourite is to park play-head at the far end, and hit “E” for Extend Selected Edit to Playhead.
But unless we know how many clips and sources involved, it is difficult to nail the right way. And, often, as is, 10 different people will give you 20 different answers.
If you want to be “cruel” to the client, if they haven’t already seen the rushes, maybe share the original with them?
You could also “Zoom In” on every second shot to change the frame, but that won’t work if you’ve done a radio edit and cut every 2 seconds.
Just a few thoughts.
Hope that they are helpful.
